[PULL 02/25] build-sys: prevent meson from downloading wrapped subprojects

[Paolo Bonzini]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

The following patches are going to introduce meson wrap dependencies,
which is a solution to download and build missing dependencies.

The QEMU build-system would do network access with no way to avoid the
fallback. As a start, hardcode "--wrap-mode=nodownload" in configure, so
that wraps would be used only after a conscious decision of the user to
use "meson subprojects download" (before running configure).
