cmake: fix `HAVE_GNUTLS_SRP` detection after adding local FindGnuTLS module

When GnuTLS is detected via pkg-config on a non-default path, e.g. with
Homebrew arm64 (`/opt/homebrew/`).

This was a regression from a commit made in this release cycle.

The Find module doesn't return an absolute path to the detected library
(as the former solution did), but a bare libname and a libpath. We thus
need to explicitly use the libpath while detecting a feature in GnuTLS
found this way. Syncing this with other dependencies.

Follow-up to 1966c86d71eb90beeeb3ccbefd6321bd64992553 #19163

Closes #19360
