[platform-releng-dev] Build schedule update through M7

[David M Williams <david_williams@xxxxxxxxxx>]

I've checked and updated the build schedule
through M7, with means "rest of March and April". I'll do May
and June later.

Please check and let me know if I've
missed (or, mis-typed) anything. It is pretty straightforward since just
one build stream! I did leave the Saturday "nightlies" at 3 PM
to make sure tests finish before Hudson recycles. Otherwise, pretty ordinary.
