Convert SKIP_(NO|COARSE|FINE)PROFILE to RUN_(NO|COARSE|FINE)PROFILE

should be explicitly enabled, not disabled.

Tunings: similar structure to monitors

Make discover_script common for monitors and tunings.
Run all tunings specified in $RUN_TUNINGS.
Create a simple tuning from the sysctl stub setting vm.dirty_ratio in
run-mmtests.sh -> tunings/tuning-sysctl.sh

Stats: All the config files contain this line:
    #export VM_DIRTY_RATIO=20
Added #export RUN_TUNINGS to be uncommented together with the former one.
