ima: rework CONFIG_IMA dependency block
[ Upstream commit 91e326563ee34509c35267808a4b1b3ea3db62a8 ]
Changing the direct dependencies of IMA_BLACKLIST_KEYRING and
IMA_LOAD_X509 caused them to no longer depend on IMA, but a
a configuration without IMA results in link failures:
arm-linux-gnueabi-ld: security/integrity/iint.o: in function `integrity_load_keys':
iint.c:(.init.text+0xd8): undefined reference to `ima_load_x509'
aarch64-linux-ld: security/integrity/digsig_asymmetric.o: in function `asymmetric_verify':
digsig_asymmetric.c:(.text+0x104): undefined reference to `ima_blacklist_keyring'
Adding explicit dependencies on IMA would fix this, but a more reliable
way to do this is to enclose the entire Kconfig file in an 'if IMA' block.
This also allows removing the existing direct dependencies.
