nfsd: v4 support requires CRYPTO_SHA256

BugLink: https://bugs.launchpad.net/bugs/1862227

commit a2e2f2dc77a18d2b0f450fb7fcb4871c9f697822 upstream.

The new nfsdcld client tracking operations use sha256 to compute hashes
of the kerberos principals, so make sure CRYPTO_SHA256 is enabled.

Fixes: 6ee95d1c8991 ("nfsd: add support for upcall version 2")
