system/man-db: Silence the mandb trigger

It's kinda hard to watch for apk warnings/errors if every invocation
(that installs man pages) is followed by a screenful of mandb
diagnostics.

mandb also prints warnings and some progress info to stderr, so we'll
still notice if there are problems.

* GLX RTS does nothing now.  Remove with extreme prejudice.

* Wayland libs are no longer shipped with Mesa, so remove Wayland dep.

* Support Amber Lake and Whiskey Lake GPUs.
