udevadm_info should use maxsplit=1 instead of maxsplit=2

In udevadm_info the below code is called to split output lines:
    key, value = line.split('=', 2)

It can lead to unhandled exception if there are more than one
equal sign in the string as split will return array of three
or more elements. The correct way to get only two elements is
to use maxsplit=1:
    key, value = line.split('=', 1)

And adding tests/unittests/test_udev.py unittest
