xfree86: bus: remove xfree86 and few other references from OS files

Conceptually, os-support should have only a basic set of OS helpers which
wouldn't mix with any DDX common structure (e.g. windowing structures, etc)

This patch removes some xfree86-only and a few other unused references from
os-support/bus.
