- Linux: olive-render-worker had no install rule, so it was missing
from the AppImage, deb, rpm and Arch packages even though
RenderWorkerPool spawns it from applicationDirPath(); install it next
to oak-editor (verified: RPATH resolution of libffmpeg_bridge works
for editor, worker and liboakgl from the installed layout)
- Windows: ffmpeg_bridge.dll is built outside app/ and is invisible to
the ntldd dependency walk, so the NSIS installer shipped without it
(and without the av*.dll it pulls in); copy it explicitly and include
it in the dependency loop
- AppImage verification now also checks oak-render-worker, liboakgl.so,
libffmpeg_bridge.so and ldd resolution of all shipped binaries
