This is a spiritual follow-up to commit 8cff531520, which
added `G_TEST_OPTION_ISOLATE_DIRS` to the `gdbus-connection-flush` test
to avoid its D-Bus cookie lock file from being erroneously deleted by
other tests running in parallel.
The same failure mode could affect any of the other D-Bus tests which
connect to a bus. As an easy fix, enable `G_TEST_OPTION_ISOLATE_DIRS`
for all of them.
The only test it’s not (yet) enabled for is `gdbus-address-get-session`
as that messes around with `XDG_RUNTIME_DIR` to test finding the session
bus. It might be possible to use `G_TEST_OPTION_ISOLATE_DIRS` with it,
but that would take longer than I have right now.
In any case, the more tests (which try to connect to a bus) that this is
enabled for, the lower the chances of spurious test failure due to them
conflicting over shared resources.
