crypto: testmgr - stop checking crypto_ahash_alignmask

Now that the alignmask for ahash and shash algorithms is always 0,
crypto_ahash_alignmask() always returns 0 and will be removed.  In
preparation for this, stop checking crypto_ahash_alignmask() in testmgr.

As a result of this change,
test_sg_division::offset_relative_to_alignmask and
testvec_config::key_offset_relative_to_alignmask no longer have any
effect on ahash (or shash) algorithms.  Therefore, also stop setting
these flags in default_hash_testvec_configs[].
