Mitchell Hashimoto 5cb7355814 builder/docker: change commit to the opt-in, special case build steps
/cc @andytson - Wanted to CC you in here so you could see some changes I
made.

First, I changed commit to opt-in, so you set "commit": true to get
commit behavior. This simplifies the logic a bit. Then, I removed the
skipping for StepExport and StepCommit and put that into the Builder
itself. This simplifies those steps (limits abstraction leakage).
Otherwise, everything looks great!
