[Test] Prevent unit-test errors in slow systems

In slow systems such as QEMU-ARM, a few test cases fail often.

- Add dynamic timeout for pipeline start
- Add mutex for sink callbacks

Changes in v2:
- Loop of wait_for_start runs if it's READY || PAUSED
- Wait 50us right after start() before state-checking.
