[thrift] fix Ruby codegen: capitalize module name for enums

Summary: all module names must be capitalized in Ruby -- if the enum name from the interface isn't capitalized \
         then it's a runtime error, e.g. in fb303_types.rb:

         -module fb_status
         +module Fb_status

Test Plan: fb303 now works with Ruby binding

Revert: OK
