perf trace: Add getrandom 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 âsyscall_arg__scnprintf_getrandom_flagsâ:
  builtin-trace.c:1113:14: error: âGRND_RANDOMâ undeclared (first use in this function)
    P_FLAG(RANDOM);
                ^
  builtin-trace.c:1114:14: error: âGRND_NONBLOCKâ undeclared (first use in this function)
    P_FLAG(NONBLOCK);
              ^
