seccomp: allow process_vm_readv to video_device on aarch64

Browse source 
libvda uses libmojo which uses libbase-core.so from libchrome.

After a recent change, libase-core.so's EarlyFeatureAccessTracker tracks
early accesses to features and saves the stacks of the callers using
libunwind.  On aarch64, libunwind can use process_vm_readv.
