lib/crypto: ensure generated *.S files are removed on make clean

make clean does not check the kernel config when removing files. As
such, additions to clean-files under CONFIG_ARM or CONFIG_ARM64 are not
evaluated. For example, when building on arm64, this means that
lib/crypto/arm64/sha{256,512}-core.S are left over after make clean.

Set clean-files unconditionally to ensure that make clean removes these
files.
