916BGAI 44c420e28b fix: prevent black screen after application upgrades ...

Serialize service operations and finish migration before starting services.
Install the startup script atomically, remove recursive restarts, and keep
the migration marker until required changes succeed.

Claim video ownership before clearing orphan VENC/VPSS resources, always
finish recovery SYS cleanup, and retain resource state on teardown failures.
Rebuild the bundled libkvm_mmf.so with these fixes.

Validated cross-builds, ABI and recovery failure paths, plus a 2.4.3 to 2.5.3
upgrade on hardware with 1080p browser WebRTC and MJPEG playback.
