[PATCH v2 3/5] dump: Recognize "fd:" protocols on Windows hosts

[Markus Armbruster <armbru@redhat.com>]

A few QMP command can work with named file descriptors.

The only way to create a named file descriptor used to be QMP command
getfd, which only works on POSIX hosts.  Thus, named file descriptors
were actually usable only there.

They became usable on Windows hosts when we added QMP command
get-win32-socket (commit 4cda177c601 "qmp: add 'get-win32-socket'").

Except in dump-guest-memory, because qmp_dump_guest_memory() compiles
its named file descriptor code only #if !defined(WIN32).

Compile it unconditionally, like we do for the other commands
supporting them.
