seccomp.2: Use syscall() in the example code
Since seccomp() doesn't exist in glibc, avoid relying on it, and use
syscall() instead. This updates the example program to match the
documentation, which was updated in commit 5945cd7bd3c3 ("seccomp.2:
Use syscall(SYS_...); for system calls without a wrapper").
