Xavier Claessens d86a6715e1 aja: Replace global semaphore with per-device flock() 
The global semaphore was never closed/unlinked, causing permission
denied issue if the device is later used by another user. Properly
removing the semaphore when stopping the pipeline would still leave it
open in case of a crash.

With a GStreamer specific name, it was also not preventing other apps to access
the device concurrently.

Finally, if the system has multiple cards, the lock should be per card
and not global (to be confirmed).

Fixes: #3283.
