[PATCH] x86/ima: fix the Kconfig dependency for IMA_ARCH_POLICY

[Nayna Jain]

If enabled, ima arch specific policies always adds the measurements rules,
this makes it dependent on CONFIG_IMA. CONFIG_IMA_APPRAISE implicitly takes
care of this, however it is needed explicitly for CONFIG_KEXEC_VERIFY_SIG.

This patch adds the CONFIG_IMA dependency in combination with
CONFIG_KEXEC_VERIFY_SIG for CONFIG_IMA_ARCH_POLICY
