fix(build): include omitted lib dir

When packaging the Ruby Pact binaries, I initially removed the `lib` dir
naively believing that the Pact binaries were static. This is in fact
incorrect, and I adjusted the extraction to extract _all_ of the
content (and only remove the README.md).

The unit tests all passed which affirmed my initial belief.
Unfortunately (as I have now discovered), the unit tests mock out the
call to the binaries, and therefore the test suite did not actuall test
the execution of the binaries.
