seccomp: Rename SECCOMP_RET_KILL to SECCOMP_RET_KILL_THREAD

Browse Source 
In preparation for adding SECCOMP_RET_KILL_PROCESS, rename SECCOMP_RET_KILL
to the more accurate SECCOMP_RET_KILL_THREAD.

The existing selftest values are intentionally left as SECCOMP_RET_KILL
just to be sure we're exercising the alias.

@@ -87,11 +87,11 @@ Return values
A seccomp filter may return any of the following values. If multiple
filters exist, the return value for the evaluation of a given system
call will always use the highest precedent value. (For example,
``SECCOMP_RET_KILL`` will always take precedence.)
``SECCOMP_RET_KILL_THREAD`` will always take precedence.)
In precedence order, they are:
``SECCOMP_RET_KILL``:
``SECCOMP_RET_KILL_THREAD``:
Results in the task exiting immediately without executing the
system call. The exit status of the task (``status & 0x7f``) will
be ``SIGSYS``, not ``SIGKILL``.
