- exec_t belongs to service.h, the main place where it is used/needed
- code for executing exec_t is moved to runsvc for the same reason
- what is left are NORETURN and ARRAY_SIZE
- the former can be replaced with direct attribute usage since
the only relevant compilers all support the attribute.
- the later is only used in 3 places and can be trivially replaced
with direct usage of sizeof().

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.

We no longer need to keep entire scripts in init program (i.e. saving space)
and reduce the code and complexity of the init program.
The runsvc tool can later be extended to do more complex child setup, such
as configuring namespaces or seccomp without adding complexity or memory
footprint to init.
