init: call clean_temp always at exit

This is has the same behaviour as before, i.e. clean_temp called at all exits
and it is similar to what was there before https://trac.osgeo.org/grass/changeset/73336, i.e. .tmp deleted at exit.
Additionally this calls clean_temp also in some error states when then
exist function calls in the call are not reached.

See https://trac.osgeo.org/grass/ticket/3635 for removal of Python-based clean up procedures (which should be covered by clean_temp).
