Average and maximum residency numbers in nofib broken

Measuring average and maximum residency in nofib is currently broken:

<<ghc: 55717832 bytes, 32 GCs (29 + 3), 0/0 avg/max bytes residency (0 samples), 58859672 bytes GC work, ...

I think that this line in runstdtest.prl was responsible for matching on -S output, but since this commit, we only do -s for performance reasons. There's this bit of outcommented code that probably does what we want.

It seems that residency numbers were the only metrics depending on -S. I don't think there's a way to recover average residency with -s alone.
