seccomp: test SECCOMP_USER_NOTIF_FLAG_CONTINUE
Test whether a syscall can be performed after having been intercepted by
the seccomp notifier. The test uses dup() and kcmp() since it allows us to
nicely test whether the dup() syscall actually succeeded by comparing whether
the fds refer to the same underlying struct file.
