Per b/31553927, the last use of this is long gone. This cipher has been
deprecated since it was (re)-added in 2015, so it's long past time to
remove it.
Update-Note: TLS_RSA_WITH_NULL_SHA is no longer available. Nothing
should be enabling it anymore. Callers using
SSL_CTX_set_strict_cipher_list instead of SSL_CTX_set_cipher_list will
notice if they're affected very quickly, because the functino will
fail if this cipher is referenced. As a deprecated cipher suite, this
cipher was already unavailable unless explicitly named, so if your
configuration doesn't say "TLS_RSA_WITH_NULL_SHA" or "NULL-SHA", you
were not using this cipher.
