Fabricio Voznika eaac94d91c Use RET_KILL_PROCESS if available in kernel
RET_KILL_THREAD doesn't work well for Go because it will
kill only the offending thread and leave the process hanging.
RET_TRAP can be masked out and it's not guaranteed to kill
the process. RET_KILL_PROCESS is available since 4.14.

For older kernel, continue to use RET_TRAP as this is the
best option (likely to kill process, easy to debug).

in R mode and could deadlock if a writer comes in between.
