Bug 1404946 - Rename wait module to sync. r=whimboo

testing/marionette/wait.js originally contained a utility for
poll-waiting on a condition.  The module has since been expanded to
also include TimedPromise, which is a specialisation of Promise that
is rejected after a duration.

The latter is not a wait utility but a synchronisation primitive.
This terminology also covers the first, and this change renames the
wait module to sync.
