Add formula for GNU Linear Programming Kit

Provides a library and stand-alone tool for solving linear programs (LPs) and
integer linear programs (ILPs). Doesn't depend on anything else.
s/require 'brewkit'/require 'formula'/g

brewkit.rb changes ENV destructively, so lets not do that everytime a formula
is required. Now it's possible for other tools to require a formula
description without worrying about side-effects.
Updated formula: glpk 4.42
