Patch steam udev rules for systemd 258

Systemd 258 requires any udev rules that adds to uaccess tag to have an ACTION!="remove" on the udev line. Steam's udev file does not have this, and is causing issues on multiple distros.

Therefore, I have created this merge request to patch the udev rules to work. This is rather urgent, as a lot of controllers are listed here and a lot of people probably rely on this to have their controllers work in other software without realizing it.
