cleanup: initd: simplify and merge linux specific code into main.c

Targetting anything else than Linux isn't really relevant. All
other systems ($BSD and other Unices) are a closed ecosystem
where kernel & userspace are developed together. They don't need
something like a third party init system, so compatibillity can
be largely ignored.
