Subject: bpf: export bpf_event_output()
Patch-mainline: v4.18-rc1
Git-commit: 6cb5fb3891db9d3f6feb0f7669946550c9abc420
References: bsc#1109837

bpf_event_output() is useful for offloads to add events to BPF
event rings, export it.  Note that export is placed near the stub
since tracing is optional and kernel/bpf/core.c is always going
to be built.
