perf trace: Add seccomp beautifier related defines for older systems

Were the detached tarball (make perf-tar-src-pkg) build was failing because
those definitions aren't available in the system headers.

On RHEL7, for instance:

  builtin-trace.c: In function ‘syscall_arg__scnprintf_seccomp_op’:
  builtin-trace.c:1069:7: error: ‘SECCOMP_SET_MODE_STRICT’ undeclared (first use in this function)
    P_SECCOMP_SET_MODE_OP(STRICT);
         ^
  builtin-trace.c:1069:7: note: each undeclared identifier is reported only once for each function it appears in
  builtin-trace.c:1070:7: error: ‘SECCOMP_SET_MODE_FILTER’ undeclared (first use in this function)
    P_SECCOMP_SET_MODE_OP(FILTER);
         ^
  builtin-trace.c: In function ‘syscall_arg__scnprintf_seccomp_flags’:
  builtin-trace.c:1091:14: error: ‘SECCOMP_FILTER_FLAG_TSYNC’ undeclared (first use in this function)
    P_FLAG(TSYNC);
                ^
