udevadm trigger: allow matching by device name
This makes udevadm trigger mirror udevadm info, except that multiple device names can be specified. Instructions in 60-keyboard.hwdb should now actually work. udevadm(8) is updated, but it could use a bit more polishing. https://bugs.freedesktop.org/show_bug.cgi?id=82311
