[libvirt] [PATCH] tests: work with older dbus

[Eric Blake]

On RHEL 5, with dbus 1.1.2, compilation failed with:

virsystemdmock.c: In function 'dbus_connection_send_with_reply_and_block':
virsystemdmock.c:68: warning: implicit declaration of function 'dbus_message_set_serial'

Fix this by instead bypassing all attempts to use a dbus serial.

* tests/virsystemdmock.c (dbus_message_set_reply_serial): Add new
override.
(dbus_connection_send_with_reply_and_block): No longer bother with
the serial.

I'm tempted to push this under the build-breaker rule, but it is
still pending a review of this patch also for RHEL 5:
