libloc: ship a more recent database by default

libloc: ship a more recent database by default

The database we ship by default is meanwhile four weeks old, and since
the merge window for Core Update 154 is still open, there is no need to
ship data being more outdated than they have to be. :-)

The second version of this patch also updates the checksum for the
downloaded database file.
