[PATCH] kbuild: correctly skip tilded backups in localversion files

Browse source 
Tildes as in path as in filenames are handled correctly now:
 only files, containing tilde '~', are backups, thus are not valid.

 [KJ]:
 Definition of `space' was removed, scripts/Kbuild.include has one.
 That definition was taken right from the GNU make manual, while Kbuild's
 version is original.
