Update reline and suppress Fiddle issue

This reverts commit 6494603510, reversing
changes made to 5d3b8f8030.

By defining the missing constant early in startup we can force
reline to detect Fiddle as version '0.0.0' when the class is provide
by a Ruby 2.x implementation that has an documented version.
