Fix space leak in fsck and drop commands.

The space leak was somehow caused by this line:

	absfiles <- mapM absPath files

I confess, I don't quite understand why this caused bad buffering,
but apparently the whole pipeline from git-ls-files backed up at that
point.

Happily, rewriting the code to only get the cwd once and use a pure
function to calculate absfiles clears it up, and should be a little more
efficient in syscalls too.
