REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4698
The default drbg type of randlib has been switched to aes_256_ctr in
openssl1.1.1, so sha1 is not really used in RandomSeed(). Remove related code
which do SHA-1 support checking in CryptRand.c and CryptRandTsc.c to avoid
potential compatibility errors.
