[PATCH] staging: crypto: skein: depend upon CRYPTO

[Jason Cooper]

Fengguang's randconfig kernel build tester discovered the following
warnings:

warning: (CRYPTO_THREEFISH) selects CRYPTO_ALGAPI which has unmet direct dependencies (CRYPTO)
warning: (DM_VERITY && CRYPTO_SKEIN) selects CRYPTO_HASH which has unmet direct dependencies (CRYPTO)

Fix this in the Kconfig by depending on CRYPTO.
