[PATCH] clean: only lstat files in pathspec

[David Turner <dturner@twopensource.com>]

Git clean takes a list of paths to clean.  Make sure that it only
lstats files which match that list of paths.  Previously, if another
process was deleting files outside of the specified paths, clean might
have failed when attempting to lstat those files.  Now, it will not
lstat them, and thus will not fail.
