unix: Include upip as fronzen modules inside the standard interpreter.

MicroPython doesn't come with standard library included, so it is important
to be able to easily install needed package in a seamless manner. Bundling
package manager (upip) inside an executable solves this issue.

upip is bundled only with standard executable, not "minimal" or "fast"
builds.
