Hou Tao	fa7f17d066	bpf/selftests: Add test for writable bare tracepoint ... Add a writable bare tracepoint in bpf_testmod module, and trigger its calling when reading /sys/kernel/bpf_testmod with a specific buffer length. The reading will return the value in writable context if the early return flag is enabled in writable context.
