I would rather have all the O_* compat defines at one place then
scattered through our code.

We have the O_CLOEXEC in src/internal.h, O_DIRECT in these two files
and following patch adds guard around O_BINARY in
src/util/virfdstream.c.

I'll leave it up to you if decide to group all of them or leave it as
it is.
