Fix three issues with resctrl selftests.
The signal handling fix became necessary after the mount/umount fixes.
The other two came up when I ran resctrl selftests across the server fleet in our lab to validate the upcoming CAT test rewrite (the rewrite is not part of this series).
These are developed and should apply cleanly at least on top the benchmark cleanup series (might apply cleanly also w/o the benchmark series, I didn't test).
v2: - Include patch to move _GNU_SOURCE to Makefile to allow normal #include placement - Rework the signal register/unregister into patch to use helpers - Fixed incorrect function parameter description - Use return !!res to avoid confusing implicit boolean conversion - Improve MBA/MBM success bound patch's changelog - Tweak Cc: stable dependencies (make it a chain).
