seccomp: Move prctl in gpu_common to gpu-specific section

Browse source 
The top part of gpu_common.policy is supposed to match
common_device.policy, but "prctl" is in this top part and isn't in
common_device.policy. A bit of history:
* prctl used to be in the common_device.policy but was removed in
  <https://crrev.com/c/2837307>.
* Even when prctl was in common_device.policy, it had different
  arguments than what we allow in gpu_common.policy.

This is a no-op cleanup change.
