[PATCH v4 0/3] t: improve compatibility with NixOS

Hi,

this is the fourth version of my patch series to improve compatibility of our test suite with NixOS.

Three changes compared to v3:

    - Switched from `test <expr> -a <expr>` to `test <expr> && test
      <expr>`.

    - Improved the commit message to explain why the new
      runtime-detected paths are only used as a fallback.

    - Rebased on top of 0e3b67e2aa (ci: add support for GitLab CI,
      2023-11-09), which has been merged to `next` and caused conflicts.

Technically speaking this series also depends on 0763c3a2c4 (http: update curl http/2 info matching for curl 8.3.0, 2023-09-15), without which the tests will fail on NixOS machines with a recent libcurl.

    +    Note that the new runtime-detected paths will only be used as a fallback
    +    in case none of the hardcoded paths are usable. For the PATH lookup this
    +    is because httpd is typically installed into "/usr/sbin", which is often
    +    not included in the user's PATH variable. And the module path detection
    +    relies on a configured httpd installation and may thus not work in all
    +    cases, either.
