integration-test: Move to using umockdev

Browse source 
Setting $SYSFS_PATH does not work any more with recent libudev versions, our
homwbrew sysfs sandbox building limits us to coldplug tests only. umockdev
works with both old and new libudevs and can also emulate uevents for future
hotplugging tests.

Skip the test if umockdev is not available, so that check and distcheck don't
bail out.
