    Remove support for old volatile udev rules below /dev/.udev
    
    Udev stopped supporting volatile udev rules in /dev/.udev/rules.d in
    udev 176, released 2012-01-11 [1].  The oldest supported distributions
    use much more recent combined systemd and udev releases.
    
        Distro            EOL        udevadm -V
        Debian 9          2022-Jun   232
        RHEL / CentOS 7   2024-Jun   219
        Ubuntu 18.04 LTS  2023-Apr   237
    
    Now udev only reads volatile rules from /run/udev/ruled.d [2].  Simplify
    the code a little.

        "A writable /run directory (ususally tmpfs) is required now for a
        fully functional udev, there is no longer a fallback to /dev/.udev."
    [2] man 7 udev
        "RULES FILES
        The udev rules are read from the files located in the system rules
        directory /usr/lib/udev/rules.d, the volatile runtime directory
        /run/udev/rules.d and the local administration directory
        /etc/udev/rules.d."
