offload/test bpf: support InProcessTethering

InProcessTethering runs as system_server (uid/gid AID_SYSTEM)
instead of as the network_stack (uid/gid AID_NETWORK_STACK).

Additionally only the network_stack has access to the default
selinux context of /sys/fs/bpf/tethering, which is fs_bpf_tethering,
so we need to use 'fs_bpf_net_shared' instead.
