meta-phosphor: fix phosphor-rootfs-postcommands

An upstream openembedded-core commit[1] changed the order of
ROOTFS_POSTPROCESS_COMMAND such that the upstream extrausers.bbclass
content runs _first_.  Some layers, such as meta-ibm, leverage
extrausers to add users to groups.  An example is adding 'admin' to the
'redfish' group.  The previous sed invocation assumed that these groups
would be empty, which was the case when phosphor-rootfs-postcommands
ran before extrausers, but is no longer the case.

Adjust the sed invocation in phosphor-rootfs-postcommands to handle
groups with existing members when trying to add root to:
    - ipmi
    - web
    - redfish
    - priv-admin
