apparmor: clarify CRYPTO dependency

The crypto framework can be built as a loadable module, but the
apparmor hash code can only be built-in, which then causes a
link error:

security/built-in.o: In function `aa_calc_profile_hash':
integrity_audit.c:(.text+0x21610): undefined reference to `crypto_shash_update'
security/built-in.o: In function `init_profile_hash':
integrity_audit.c:(.init.text+0xb4c): undefined reference to `crypto_alloc_shash'

This changes Apparmor to use 'select CRYPTO' like a lot of other
subsystems do.
