mptcp: select CRYPTO_LIB_UTILS instead of CRYPTO

Since the only crypto functions used by the mptcp code are the SHA-256
library functions and crypto_memneq(), select only the options needed
for those: CRYPTO_LIB_SHA256 and CRYPTO_LIB_UTILS.

Previously, CRYPTO was selected instead of CRYPTO_LIB_UTILS.  That does
pull in CRYPTO_LIB_UTILS as well, but it's unnecessarily broad.

Years ago, the CRYPTO_LIB_* options were visible only when CRYPTO.  That
may be another reason why CRYPTO is selected here.  However, that was
fixed years ago, and the libraries can now be selected directly.
