Give this condition a more revealing name
Move options to SoftwareSpec
Move dependencies to SoftwareSpec
Allow explicitly requiring universal deps

Previously, instructing Homebrew that all dependencies should be built
universal could be accomplished by redefining BuildOptions#universal? in
the class body:

  def build.universal?
    true
  end

However, the build object is no longer shared by all specs, so this is
insufficient. Instead, a new DSL method, "require_universal_deps", can
be used.

This feature is almost exclusively for wine, which requires universal
deps but does not itself have a universal option, since it is always
built 32-bit.
