    tests: Isolate directory access for gdbus-connection-flush test
    
    When multiple tests were run in parallel, this would race on its access
    to `~/.dbus-keyrings` to authenticate with the D-Bus server, since the
    keyring directory was not appropriately sandboxed to the unit test.
    
    Use `G_TEST_OPTION_ISOLATE_DIRS` to automatically isolate each unit
    test’s directory usage.
    
    This should hopefully fix the failure seen in
    https://gitlab.gnome.org/GNOME/glib/-/jobs/1849524, where the following
    was in the log for a test executed in parallel:
    ```
    GDBus-DBUS_COOKIE_SHA1: Deleted stale lock file '/home/user/.dbus-keyrings/org_gtk_gdbus_general.lock'
    ```
