[PATCH 01/18] SUNRPC: Add Kconfig dependency on CRYPTO_KRB5

[Chuck Lever]

From: Chuck Lever <chuck.lever@xxxxxxxxxx>

The rpcsec_gss_krb5 module currently contains its own Kerberos 5
crypto implementation (key derivation, encryption, checksumming)
that duplicates functionality available in the common crypto/krb5
library. As a first step toward migrating to that library, add a
Kconfig select so that building rpcsec_gss_krb5 pulls in the
common Kerberos 5 crypto support.

The per-enctype Kconfig options (AES_SHA1, CAMELLIA, AES_SHA2)
remain: they continue to gate which encryption types are offered
by the GSS mechanism. The individual crypto algorithm selects
they carry become redundant once the migration is complete, since
CRYPTO_KRB5 already selects all needed ciphers and hashes.
