test: move crypto related common utilities in common/crypto
Since `common/crypto` already exists, it makes sense to keep
crypto-related utilities there. The only exception being
common.hasCrypto which is needed up front to determine
if tests should be skipped.

Eliminate the redundant check in hasFipsCrypto and just
use crypto.getFips() directly where needed.
