As of a few days ago hydra has a different GC configuration that leads
to eval failures when the tested job has a direct dependency on all the
tests. This is an attempt at migrating the old list of jobs to the new
format while keeping the logic and the tests the same.

We want to disable `PLUGIN_AUTH_PAM` when building:

1. `mariadb` on macOS.
2. `mariadb-client` on any platform

Unfortunately, the interaction of these two commits
  6c97b04
  7e43b4d
created a situation where we disable it *twice* when building on macOS.
Once in a darwin-specific `prePatch` script, and again in the `patches`
section for client builds.

This removes the redundant `prePatch` script and conditionally applies
the patch to `mariadb` server builds on darwin.

Fixes #70835

(cherry picked from commit b0b0bb7)

Note that we need to build from a tarball now to get the vendored
crates. A bit ugly to fetch tarballs from Hydra...

[19.09] nixos/release-combined; migrate constituents list to strings

hydra-eval-jobs's derivation-patching logic cannot handle hydraJob.

'nixpkgs' is a result of a call to cleanSource, which is very
expensive and fails in --dry-run mode.

(cherry picked from commit 3182fbd)

Disables support for Javascript and PHP:
- Javascript requires an old version of v8
- PHP requires a larger number of dependencies in addition to php-embed
