Linux 2.6.26 and earlier will fail libevent's timerfd_create() call due to

  nonzero flags, yet some systems using that version have the nonworking
  flags in their header files (Debian Lenny).  Do not spew warnings in
  regress output in that case, and set epollop->timerfd = -1.  Suggested
  by Nick Mathewson.
