ima: ensure IMA_APPRAISE_MODSIG has necessary dependencies
IMA_APPRAISE_MODSIG is used for verifying the integrity of both kernel
and modules. Enabling IMA_APPRAISE_MODSIG without MODULES causes a build
break.
Ensure the build time kernel signing key is only generated if both
IMA_APPRAISE_MODSIG and MODULES are enabled.
Fixes: 0165f4ca223b ("ima: enable signing of modules with build time generated key")
