[PATCH,RFC 3/3] scripts/setlocalversion: Fix false positive -dirty tag caused by make-kpkg

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

make-kpkg modifies scripts/package/Makefile and deletes
scripts/package/builddeb as part of its build process.  Ignore these
changes so the tree isn't marked as -dirty, when it is just an
artifact of make-kpkg.  (make-kpkg clean restores the files to their
original state, and these helper scripts won't affect the final
compiled kernel in any way.)
