Modify kernfs scripts to be able to run them twice

Those scripts could only be run once, because mount errors out
if it tries to mount an already mounted fs (or unmount a non
mounted fs). This changes generation of the scripts so that

any mount is preceded with "mountpoint -q
", and any umount

is preceded with "mountpoint -q && ".
