rc: Simplify/POSIXify the autorestore.kak script

Browse Source 
This commit allows buffers that were not previously written to disk to
be restored if a backup has been generated in their name. Consequently,
we got rid of a few non-POSIX calls to `find` (using `-maxdepth` or
`-delete`), and of the logic that detected the newest backup (which
didn't seem a good reason enough to steer away from a portable command).

Fixes #1236
