[PATCH,RFC 2/3] Fix scripts/setlocalversion to avoid erroneous -dirty tag

["Theodore Ts'o" <tytso@mit.edu>]

If git's index file is out of date, and some files have been touched
such that their timestamp doesn't what is in the index, "git
diff-index HEAD" may show that a particular file is dirty, when in
fact it really isn't.  Running "git status" will update the index to
avoid these false positives.
