gitlab-ci: Decrease the size of the compiler cache

Browse source 
Uploading the cache from the runner takes a long time in the MSYS2
job, mostly due to the size of the compiler cache.
However, looking at runs with a non-poluted cache, it seems like
you can get a build with a 99% hit rate already with ~ 160 MiB cache
size, so the compiler cache with 500 MiB certainly contains a lot of
stale files. Thus decrease the size of the ccache to a more reasonable
value to speed up the MSYS2 job in our CI.

While at it, also add a "du -sh" for the build folder to get a better
feeling for the amount of object code that is required for the build,
and publish the list of files in /var/cache to be able to better
analyze what is really clogging our cache here.
