Remove old vte package from Ubuntu

[Jeremy Bícha]

NOTE
====
Debian's debian-installer (specifically cdebconf-gtk-terminal I believe) uses a udeb from the old vte package. See https://bugs.debian.org/887649

Original Bug Report
===================
The old vte source hasn't been maintained upstream since 2011 (when GNOME 3 was released). vte will be dropped from Debian Testing as soon as the debian-installer is ported. The replacement is provided by source vte2.91 (which requires gtk3).

sjterm was already requested for removal in LP: #1728241

$ reverse-depends src:vte

Hello. Guake is being ported to vte-2.91.

I guess vte usage in debian-installer for Ubuntu purposes doesn't matter much, but we would need to strip the udeb dependencies from the cdebconf-terminal before proceeding. Anyway, since the situation of the vte removal in Debian isn't quite solved yet, I don't feel the vte removal concept to be mature enough for now.

We're just going to follow Debian for this removal.
