[PATCH il/rfc-remote-fd-ext] Fix build on Windows

This adds the necessary #defines so that the programs can be built, but
since the poll emulation is not extended to support POLLOUT and POLLNVAL,
the resulting programs will most likely not function properly. (The test
does not check them, yet.)

The code doesn't really need POLLNVAL (Its just there for "can't happen"
case). POLLOUT is needed. I looked at poll emulation code: It returning
EINVAL causes transfer loop to fail quick.

I think its possible to write the loop in terms of select instead of poll.
Would this be better for Git on Windows?

No. select does not work with pipes on Windows.
