strbuf_read_once can also operate on blocking file descriptors if we are
sure they are ready. The poll (2) command however makes sure this is the
case.
Reading the manual for poll (2), there may be spurious returns indicating
readiness but that is for network sockets only. Pipes should be unaffected.
By having this patch, we rely on the correctness of poll to return
only pipes ready to read.
This fixes compilation in Windows.
