udev: use ENV{ID_DEBUG_APPLIANCE} instead of GROUP and direct uaccess

GROUP can't be used for
* It's not concrete. All users in plugdev groups can use all devices in
  plugdev group, whatever it's phone, camera, microphone or debugprobe.
* It's not flexible. The user list need be maintained manually. And if
  update, user need to re-login to take effect.
* It doesn't work on modern Linux distros. On modern Linux world, only
  Debian and its derived distros have plugdev group by default. Arch,
  Fedora and Gentoo have no plugdev group by default at all. And systemd
  have a behavior: if the group declared in GROUP="" doesn't exist or
  isn't system group, it will ignore the whole udev rule line (not only
  the chown operation). So our rule won't work on most modern Linux.

Direct uaccess rule shouldn't be used because according to the post of
systemd developer[1], the generic device class should be used instead.

Since systemd has ID_DEBUG_APPLIANCE generic device class, we use it
directly.

The hint of probe-rs main program also need to be updated, to fix the
issue mentioned in [2].
