qemu-2.10.1.bb: support mingw build

The patch chardev-connect-socket-to-a-spawned-command.patch calls
"socketpair". This function is missing in mingw, so the patch
needs to be modified accordingly, otherwise we end up with a broken
mingw build.
While it is possible to simply remove the patch on a recipe level for
mingw platform, it makes more sense to modify the patch itself.
