@make: move MaybeSubMake to job.c

Simplify MaybeSubMake to work on the expanded command from
JobWriteCommand, we check for progname sans any "[level]".

This improves reliability and reduces overhead as we only
scan commands that will actually be run - in jobs mode.

In meta_oodate we need to know of OP_SUBMAKE when deciding if
a .meta file is needed or not - and therefor needs checking.
This obviously happens before JobWriteCommand is called, so we may
have to check MaybeSubMake from meta_needed. If so, we set a flag
doneSubmake so JobWriteCommand will not recheck.

Tweak the few unit-tests that are impacted.
In particular; we have to use a symlink .make -> ${MAKE} to be able
to defeat MaybeSubMake and trigger warnings about bogus -J args.

@make: add on-demand inter-process stack traces

When debugging a build that heavily uses nested calls to sub-makes, the
chain of calls is useful to quickly assess the situation.  If explicitly
requested, include the actions from any parent processes in the stack
traces.
