[PATCH] opkg-utils: Add basic PACKAGECONFIG for python dependencies

[Richard Purdie <richard.purdie@linuxfoundation.org>]

In small configurations its useful not to have python dependencies. This
patch adds code to disable those using PACKAGECONFIG. This allows us to
fix poky-tiny after the recent move of update-alternatives to opkg-utils.
