tests: Allow usage of externally overridden pkg-config
Hi all,
This addresses an issue I found some time ago when running the tests, in that a native file can override pkg-config
but, if done, this override is not taken into account for the tests.
In https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5196 it was suggested that I should either upstream the patch, or wait for https://github.com/mesonbuild/meson/pull/11007#issuecomment-1684228472 to be merged. Since the Meson PR was closed, I'm hereby taking the former step.
Please let me know what you think.
