cbuildbot: if --remote --debug, make sure the user knows it.

Basically, this maps back to the fact we're overloading --debug
into --dry-run (they *are* different).  That needs resolution
sooner rather than later.

In the interim since I just sat working on other things for the
last 3 hours waiting on tryjobs that never were actually submitted
due to --debug, modify cbuildbot to output a notice that if
--remote --debug was used, jack all was actually done.

BUG=None
TEST=None
