pg_dump: tests: Correct test condition for invalid databases

For some reason I used not_like = { pg_dumpall_dbprivs => 1, } in the test
condition of one of the tests added in in c66a7d75e65. That doesn't make sense
for two reasons: 1) not_like isn't a valid test condition 2) the database
should not be dumped in any of the tests.  Due to 1), the test achieved its
goal, but clearly the formulation is confusing.  Instead use like => {}, with
a comment explaining why.
