Fixes g-ir-scanner breakage that seems to happen with latest Meson 1.6.0.

We use rustup to source our rustc toolchain, however
due to rust being a common dependency, the toolchain
might get install when installing build depds of
packages.
Ensure rust can cargo are removed if that happens

This is mostly done to remove the hardcoded HOME
env var that ci-templates appends to the image. See [1]

But it also allows us to add extra things useful for local
development to it, as long they don't interfere with the
build enviornment.
This also means we can switch the build image to be based
on top of the normal fedora one rather than toolbox,
so it will no longer advertise the toolbox compatible labels
since it was buggy anyway.

This adds roughly 3 GB to the CI image, but assures us that we will
have most of debug symbols installed, minus a some big ones we
don't need and filter out.
The size increase is not that impactful as it's a one time cost,
since the images get cached in the runners afterwards.
This will improve stacktraces we get from the CI and validate.
