Modified Files:
        src/sys/miscfs/fifofs: fifo_vnops.c
        src/tests/kernel/kqueue/write: t_fifo.c

Log Message:
- Add a new EVFILT_WRITE test case for FIFOs that correctly validates
  the writability thresholds.
- Fix a bug in fifo_kqfilter() exposed by the new test case; in the
  EVFILT_WRITE case, we were attaching the wrong end of the socket
  pair to the knote!
- In filt_fiforead(), use ">= so->so_rcv.sb_lowat" rather than "> 0"
  for consistency with fifo_poll().  NFC.
