Allow system_server to write to bpf maps
The bpf maps for per uid stats need to be regularly cleaned now to
optimize the memory usage and performance. It can only done by
system_server since it is the process that scrapes and read the stats.
So allow it to write to maps to clean the stats. This change also
allows the system server to create PF_KEY sockets since we need a
reliable way to force synchronize the rcu on devices with 4.9 kernel.
