write some basic metadata values as early as possible
There are a few metadata values that, if they are missing from
metadata.json, make the metadata file break gather_builder_stats. Now
that the metadata object is preserved across cbuildbot re-executions,
write some important values to metadata as soon as possible (at the very
beginning of the run) rather than waiting until after a SyncStage has
run.
