WriteFile() returns ERROR_NO_DATA when writing to a pipe that is
"closing", however by default the write() wrapper in the CRT maps this
to EINVAL so we get confusing things like

  hPutChar: invalid argument (Invalid Argumnet)

when piping the output of a Haskell program into something that closes
the pipe early.  This was happening in the testsuite in a few place.

The solution is to map ERROR_NO_DATA to EPIPE correctly, as we
explicitly check for EPIPE on stdout (in GHC.TopHandler) so we can
exit without an error in this case.
