Scan /sys/class rather than /sys/dev to populate all devices.

Fixes #26 #63 #69

I just tried the patch. It doesn't fix Pipewire, Pipewire requires SOUND_INITIALIZED to be set to 1. I think this patch needs to be adapted to work with this one. #69

I realized that when I checked the makefile. Anyways, for now I am using your patch + the pipewire one after tweaking it a bit. Its been great! I was able to play Counter Strike:Source and play music, no problems whatsoever.

I'm concerned about potential performance issues here as this seems to be quite slow compared to the previous method. I'm not sure why exactly but things using libudev-zero definitely take longer to start up than before.

Both /sys/dev and /sys/class are symlink farms for /sys/devices.

/sys/dev lacks anything without a major:minor, whereas /sys/class should have everything.

/sys/devices should be insignificantly faster due to less symlink resolutions, but should ensure walking the tree in canonical order.
