tests/kms_lease: exercise uevent
And make sure we get the LEASE=1 value, indicating a lessee change.
v2: Apparently netlink reading can leak EAGAIN out through
udev_monitor_receive_device. No idea what's going on there, so let's
wrap some duct tape around it.
v3: Lyude reported that we might get a few udev events on startup of
the test. Drain those first.
v4: Use the igt hotplug library functions, they already take care of
all the uevent special cases.
