meta-phosphor: remove obmc-fru-ipmi IMAGE_FEATURE

There is currently a lot of complexity of setting up an image feature
which is only used to enable the fru-device feature of entity-manager.
Simplify this by using RRECOMMENDS, in entity-manager, and eliminating
the IMAGE_FEATURE.

Tested:

Ran `bitbake entity-manager -ne` and observed the following on two
affected platforms:

In witherspoon:
```
 # $PACKAGECONFIG [5 operations]
 #   :remove[pn-entity-manager] openbmc/openbmc/meta-ibm/conf/machine/witherspoon.conf:41
 #     "ipmi-fru"
 #   set openbmc/openbmc/meta/conf/documentation.conf:321
 #     [doc] "This variable provides a means of enabling or disabling features of a recipe on a per-recipe basis."
 #   set openbmc/openbmc/meta-phosphor/recipes-phosphor/configuration/entity-manager_git.bb:14
 #     [_defaultval] "ipmi-fru"
 #   set openbmc/openbmc/meta-phosphor/recipes-phosphor/configuration/entity-manager_git.bb:15
 #     [ipmi-fru] "-Dfru-device=true, -Dfru-device=false, i2c-tools,"
 #   set openbmc/openbmc/meta-phosphor/recipes-phosphor/configuration/entity-manager_git.bb:18
 #     [validate-json] "-Dvalidate-json=true,                                 -Dvalidate-json=false,                                 ${PYTHON_PN}-jsonschema-native"
 # pre-expansion value:
 #   "ipmi-fru"
 PACKAGECONFIG=""
```

In p10bmc:
```
 # $PACKAGECONFIG [7 operations]
 #   :append[pn-debug-trigger] openbmc/openbmc/meta-ibm/conf/machine/p10bmc.conf:72
 #     " triggers"
 #   :remove[pn-entity-manager] openbmc/openbmc/meta-ibm/conf/machine/p10bmc.conf:75
 #     "ipmi-fru"
 #   set openbmc/openbmc/meta/conf/documentation.conf:321
 #     [doc] "This variable provides a means of enabling or disabling features of a recipe on a per-recipe basis."
 #   set openbmc/openbmc/meta-phosphor/recipes-phosphor/configuration/entity-manager_git.bb:14
 #     [_defaultval] "ipmi-fru"
 #   set openbmc/openbmc/meta-phosphor/recipes-phosphor/configuration/entity-manager_git.bb:15
 #     [ipmi-fru] "-Dfru-device=true, -Dfru-device=false, i2c-tools,"
 #   set openbmc/openbmc/meta-phosphor/recipes-phosphor/configuration/entity-manager_git.bb:18
 #     [validate-json] "-Dvalidate-json=true,                                 -Dvalidate-json=false,                                 ${PYTHON_PN}-jsonschema-native"
 #   override[pn-opkg]:set openbmc/openbmc/meta-ibm/conf/machine/p10bmc.conf:74
 #     "curl openssl ssl-curl"
 # pre-expansion value:
 #   "ipmi-fru"
 PACKAGECONFIG=""
```

Built an image for yosemite4 and confirmed that fru-device is still
installed:

```
root@yosemite4:~# systemctl | grep -i Fru
  xyz.openbmc_project.FruDevice.service                                                                        loaded active     running          Fru Device
root@yosemite4:~# systemctl status xyz.openbmc_project.FruDevice.service
* xyz.openbmc_project.FruDevice.service - Fru Device
     Loaded: loaded (/usr/lib/systemd/system/xyz.openbmc_project.FruDevice.service; enabled; preset: enabled)
