Following is what happens:

  if (setgroups(gid_count, gid_list)) {
   rsyserr(FLOG, errno, "setgroups failed");
   io_printf(f_out, "@ERROR: setgroups failed\n");
   return -1;
  }

and from setgroups(2)

"
setgroups() sets the supplementary group IDs for the calling process. Appropriate privileges (Linux: the CAP_SETGID capability) are required.
"

Either CAP_SETGID is required on rsync binary or only the admin (root) user can do this, which explains why it fails for mysqld.
