We only ever set properties in the devices, so let's make that more explicit
and auto-generate the udev rule. This way we're hopefully better protected
from the various typos that hid in those rules over the years, but also be
prepared for passing the udev property key/value pairs elsewhere.

This is supposed to come from systemd on a real setup, but for our test setup
we want to pass the test suite even when the system itself doesn't set it.
The test device initialization code was a bit of duplicated boilerplate and
required adding a reference to the devices to the 'devices' list in litest.c.
Automate this with a new TEST_DEVICE macro that adds the devices to a custom
section in the binary, then loops throught that section to get the device out.
This reduces the boilerplate for each test device to just the TEST_MACRO and
the LITEST_foo device enum entry. It also now automates the shortname of the
device.
The device's shortname was standardised in this approach as well, lowercase
and dashes only.
