alpm/remove.c : respect --dbonly during remove-upgrade

When a -Sk or -Uk operation induced a removal of an existing local
package, --dbonly was not in effect and the files were all removed.

Fixing this behavior was already marked as TODO in database012 pactest
------------
TODO: I honestly think the above should NOT delete the original les, it
hould upgrade the DB entry without touching anything on the file stem.
E.g. this test should be the same as:
   pacman -R --dbonly dummy && pacman -U --dbonly dummy.pkg.tar.gz
