[PATCH] tiff: flesh out PACKAGECONFIG

[Christopher Larson <kergoth@gmail.com>]

Adds packageconfigs for all appropriate configure arguments (other than jpeg
8/12 bit mode support, where I wasn't clear on the deps, and which I doubt we
care about).

jpeg, zlib, and xz dependencies can now be controlled.
