bug 1425985 - fix fennec post-beetmover-dummy. r=bhearsum

Adjust post-beetmover-dummy's tasks and deps.

- Fennec doesn't have beetmover-repackage or beetmover-checksums,
  so add `beetmover` to the post-beetmover-dummy kind-dependencies.

- Add a fennec-promote post-beetmover-dummy job.

- Remove the extraneous -ship post-beetmover-dummy jobs.  Once we
  removed the assumption that dummy jobs had to be in the same phase,
  these became redundant.

In testing, this looks good. For the next step, we may want to split
these dummy tasks up by `build_platform`. Then downstream tasks could
then optionally filter their dummy deps by `build_platform`; this
would allow for certain platforms to proceed on to the next steps
sooner, rather than wait for the slowest platform to finish.

I also suspect we don't need post-beetmover-checksums-dummy at all;
it's redundant.
