[PATCH] meson: Build qemu-nbd on macOS again

[PATCH] meson: Build qemu-nbd on macOS again

[Thomas Huth]

Before switching to the meson build system, we used to compile qemu-nbd
for macOS, too, which is especially important for running the iotests
there. Commit b7c70bf2c5 disabled it by accident, since it did not take
into consideration that the $bsd variable in the configure script was
also set to "yes" on macOS. Fix it by enabling qemu-nbd on all systems
but Windows now instead (which was likely the original intention of the
old code in the configure script).

Fixes: b7c70bf2c5 ("meson: qemu-{img,io,nbd}")

I can queue this through my NBD tree, although if there is a batch of 
meson fixes going in sooner than that, I don't mind if it goes there.

FYI, it is pretty trivial to enable building of qemu-nbd.exe on Windows,
which eanbles the conditional to be removed from meson entirely. I've
just CC you a series todo that.
