config: android-recommended: Disable BPF_UNPRIV_DEFAULT_OFF for netd
AOSP's `netd` process fails to start on Android S:
E ClatdController: getClatEgress4MapFd() failure: Operation not permitted
I netd : Initializing ClatdController: 410us
E netd : Failed to start trafficcontroller: (Status[code: 1, msg: "Pinned map not accessible or does not exist: (/sys/fs/bpf/map_netd_cookie_tag_map): Operation not permitted"])
E netd : CRITICAL: sleeping 60 seconds, netd exiting with failure, crash loop likely!
And on Android R:
I ClatdController: 4.9+ kernel and device shipped with P - clat ebpf might work.
E ClatdController: getClatEgressMapFd() failure: Operation not permitted
I netd : Initializing ClatdController: 1409us
E netd : Failed to start trafficcontroller: (Status[code: 1, msg: "Pinned map not accessible or does not exist: (/sys/fs/bpf/map_netd_cookie_tag_map): Operation not permitted"])
These permission issues are caused by 08389d888287 ("bpf: Add kconfig
knob for disabling unpriv bpf by default") because AOSP does not provide
netd the `SYS_ADMIN` capability, and also has no userspace support for
the `BPF` capability yet.
