No displays found when running mustash on device

Project Member Reported by kylec...@chromium.org, Nov 15 2016

Issue description

When running mustash on device we no longer get any visual output. DrmNativeDisplayDelegate::GetDisplays() returns 0 displays when the callback fires so nothings gets drawn.

ozone-mus: Fix detecting displays on device in mustash.

crrev.com/429173 introduces a separate OnGpuProcessLaunched() to
GpuThreadObserver, which performs some of the initialization in
the drm backend. Update the mus-proxy in ozone to make sure this
new function is invoked in the observers before OnGpuThreadReady.
