udevadm: make use of the new uuid-enabled triggering for "udevadm trigger"
This adds two things:
- A new switch --uuid is added to "udevadm trigger". If specified a
random UUID is associated with the synthettic uevent and it is printed
to stdout. It may then be used manually to match up uevents as they
propagate through the system.
- The UUID logic is now implicitly enabled if "udevadm trigger --settle"
is used, in order to wait for precisely the uevents we actually
trigger. Fallback support is kept for pre-4.13 kernels (where the
requests for trigger uevents with uuids results in EINVAL).
