    scripts/patch-kernel.sh: do not try to check files after patch
    
    Since we are not using patch -b, *.orig files are only created when
    there are conflicts, or never according to posix patch.
    
    As such, it doesn't really make sense to always delete *.orig files
    presuming they are patch backups, even if they are patch backups.
    Doing so is both deleting potentially useful information for failed
    patch applications and creating hard to diagnose bugs [1].
    
    In a similar vein, checking for *.rej files does not add any value
    since we're already checking the patch command's return code.
