DBus: Bus::AddMatch and RemoveMatch support repeated rules.
This fix counts the number of times the same rule is added to a dbus::Bus
and removes the rule from the real DBus connection when all the copies of
the same match rule have been removed.
BUG=chromium:173054
TEST=BusTest.DoubleAddAndRemoveMatch passes.
