[Xen-devel] [PATCH OSSTEST v2] Disable proxy for all preseeded wget

At least in some contexts scripts can be run with http_proxy pointing
to the apt proxy (I noticed it in /usr/lib/base-installer.d/ hook used
for ucode installation).

Since all of these particular fetches are from a known to be local
webserver just disable proxying altogether.

With busybox wget in d-i this is done with the -Y argument.

v2: Define and use $preseed_wget.
