[Alakesh Haloi]

Without this patch we see following error while building and kselftest
for secccomp_bpf fails.

seccomp_bpf.c:1787:20: error: âPTRACE_EVENTMSG_SYSCALL_ENTRYâ undeclared (first use in this function);
seccomp_bpf.c:1788:6: error: âPTRACE_EVENTMSG_SYSCALL_EXITâ undeclared (first use in this function);
