bootstrap: Filter commandline arguments.

When invoking cbuildbot on older branches, we would pass along
cbuildbot options that didn't exist on the branch. Use cbuildbot's
existing mechanism for filtering command line options that aren't
supported by the old branch.

BUG= chromium:684887 
TEST=run_tests followed by multiple local builds.

bootstrap: bootstrap -> cbuildbot_launch.

Bootstrap is a heavily overloaded term, and I wanted to pick something
better before this goes into production and becomes locked down.

This script runs at TOT, and lauches cbuildbot to perform a build an a
branch (or not) in a safe way.
