[PATCH v6 39/41] toasterui: detect build run start correctly on Jethro

[Ed Bartosh <ed.bartosh@linux.intel.com>]

From: Elliot Smith <elliot.smith@intel.com>

We currently use the TargetsAcquired event fired by the XMLRPC
server to mark the start of a build run from the command line.
At this point, we create the Build object in buildinfohelper,
then append targets etc. to it as the run continues.

However, on Jethro, this event isn't fired. This means that we
can't support builds with the Jethro release correctly, as
a Build object is never created.

Add a condition so that we can create a Build object when building
with Jethro by falling back to the BuildStarted event. Jethro
builds which fail early (bad target, bad MACHINE, bad DISTRO etc.)
will not be captured (as we need the TargetsAcquired event for
that), but other builds which succeed or fail later will be
captured.
