From: Arnd Bergmann <arnd@arndb.de>
When module support is disabled, CONFIG_MODULE_SIG_HASH cannot be set either, so the build process fails with an error
certs/Makefile:52: *** Could not determine digest type to use from kernel config. Stop.
when IMA_APPRAISE_MODSIG is set but modules are not.
Add a Kconfig dependency to prevent this configuration.
