Disable conditions for some non-oneshot (runtime) hooks

The SVC_RECONF, SVC_LOST, SVC_START, and RUNLEVEL_CHANGE hooks are not
one-shot, they are also not regular conditions since there exist no
mechanism to reset them from flux.

One idea was to turn them into actions, but the lost + start hooks need
to be called multiple times per trigger, e.g. `initctl reload`, which
turned out to be non-trivial to implement right now.

Therefore, for (at least) the Finit v3.1 release these conditions have
been disabled ("nop") and ignored by Finit.  Only actual C-style plugins
will be called.
