Include PostgreSQL and H2 in our package

These two databases are somewhat popular for a Gerrit installation,
and their drivers don't take up that much space.  We might as well
include them, along with commons-dbcp and commons-pool, so there
is less to download and install when setting up a new Gerrit server.
