configure: Fix build dependencies with vhost-vdpa.

Browse source 
Following the same logic as for vhost-net-user and vhost-kernel,
enable vhost-net if vhost-net-vdpa is enabled and vhost-net is not
explicitly disabled.
See 299e6f19b3 ("vhost-net: revamp configure logic")

Autoselect VHOST if VHOST_VDPA is set
See 21c6b0c87e ("configure: simplify vhost condition with Kconfig")
See 2becc36a3e ("meson: infrastructure for building emulators"

Problems can be triggered using;
... --enable-vhost-vdpa --disable-vhost-user --disable-vhost-kernel ...
