Log Message:
fifo: Followups to fix previous fifo_vnops.c change.

1. Fix open so with O_RDONLY and not O_NONBLOCK, it will block as
   POSIX specifies until there are writers -- not until there are
   writers _or_ a read is possible without blocking (which is always
   immediately true because read will immediately report EOF).

   This was a regression in the previous change which I failed to
   catch because I committed the change a few days ago to hg and
   forgot that I hadn't yet run all the applicable tests when I
   exported it to CVS today -- I had only done the background
   research and thought about the semantics.

2. Clear xfail on various tests that were fixed by the change.
