fwupd: fix ptests

The ptest package requires dbus as a runtime dependency, otherwise the tests fail
with the following error:

Failed to connect to daemon: Could not connect: No such file or directory
FAIL: fwupd/fwupd.test (Child process exited with code 1)
SUMMARY: total=1; passed=0; skipped=0; failed=1; user=0.7s; system=0.1s; maxrss=21716
