test: make test-dh-regr more efficient where possible

test-dh-regr is timing out in CI because crypto.createDiffieHellman() is considerably slower after an OpenSSL upgrade. This PR modifies the change from 11ad744 which made the test FIPS-compatible. When not in FIPS mode, the test will use a shorter key which will enable it to run much faster.
