It seems to be timing out with high frequency only on Windows runners.

This might be related to the same issue described in the previous
commit: Till we can update the container image to the Feb 11 security
update, x86 executables and in general the container image will behave
badly because of:

Disable it for now.
This will reduce the excessive load on the runners which are having issues
with this job in particuliar. We will revisit when we better understand the
runners issues.
Passing regex as variable does not really works, we ended up matching the
regex as a string instead. Replace all REGEX variable with rules: override.
It is longer but more reliable.

Rules is a new feature that replaces only/except and allow for finer grain
control on the workflow. With rules, we gain finer grain to pipeline and merge
request pipelines.
The windows runner has become a bit unstable lately, might be
due to some recent update. It frequently timeouts while waiting
to pick up a job or sometimes it goes missing in the middle of a job.
This is where the WINEPREFIX is now in Cerbero. This used to be
share/wine, but was moved to var/tmp/wine for clarity. It was causing
two problems:
1. The size of these generated files are ~1GB, which were ~500MB after
tar.gz, and they were completely useless since they can just be
regenerated by Wine the next time it's run. Let's not waste egress
bandwidth.
2. Random build failures because wineserver and associated processes
would not always exit before we started tarring up the prefix, then
write to the directory on exit while tar was reading the directory
causing `tar -czf` to fail:
```
$ tar -C ${CERBERO_HOME} -czf $CERBERO_DEPS build-tools build-tools.cache dist/${ARCH} ${ARCH}.cache
tar: build-tools/share/wine: file changed as we read it

This is slightly weird, cause I am not sure what causes the clone
to be there, since gitlab-runner supposedly always either use a
clean volume or at least runs git clean on the existing ones.
But its there and so we have to deal with failures like so
https://gitlab.freedesktop.org/tpm/gstreamer-sharp/-/jobs/1672137
That job was the slowest, now each jobs takes about 12 minutes, which
makes it slightly faster then msys2 jobs, and sometime iOS due to low
bandwidth and low availibility of OSX runners.
CCache tends to consume a lot of space which taxes heavily some
of the shared runners. Limit the mahcines the job can run
to those were we can ensure they will not have issues with
the storage.
