Fix backup.sh: always clean up temp dump/tar files via EXIT trap

Browse Source 
Previously the dump/tar cleanup only ran after restic forget succeeded,
so a plaintext Postgres dump could be left behind in /tmp if tar or
restic failed partway through. Add an EXIT trap that unconditionally
removes both temp files on any exit path, and drop the now-redundant
explicit rm -f from the success path.
