build-sys: add contrib directory
Move files that are not compiled to <build-root>/contrib directory. The files consist two unmaintained commands, alternative ps & w, and and broken utmp examination / printing utility. The dummy.c became unnecessary at the point when autotools where re-introduced. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
