m4: drop redundant conditions in TLS library detections
Omit checking `OPT_<BACKEND>` against `no` twice.

Also:
- openssl: drop stray `OPT_OPENSSL=off` check.
  Follow-up to 68d89f242c #6897
- rustls: drop no-op line.
  Follow-up to 9c42098370 #13202
- gnutls: fix casing in comment.
- merge `if` branches where possible after these changes.

Closes #21781
