prctl.2, seccomp.2: Clarify that SECCOMP_SET_MODE_STRICT disallows exit_group(2) 

These days, glibc implements _exit() as a wrapper around
exit_group(2). (When seccomp was originally introduced, this was
not the case.) Give the reader a clue that, despite what glibc is
doing, what SECCOMP_SET_MODE_STRICT permits is the true _exit(2)
system call, and not exit_group(2).
