While working on some polkit stuff I found out that we are inconsistent with the
way we parse /proc/*/stat files, so I added a new helper instead along with some
tests.  Unfortunately using it for the thing I wanted is not really viable in
the end, so it "violates" the Rule of three, but at least it does something
correctly.

v3:
- Added an enum with names for the fields of the file
- Made this not limited to linux as that was the way it worked in qemu before

v2:
- https://listman.redhat.com/archives/libvir-list/2021-November/msg00606.html
- Fixed open64 by just using virFileReadAllQuiet instead of g_file_get_contents
- Removed some leftover unused variables
- Still do not know why my cirrus builds fail

v1:
