[DRE-maint] Bug#725115: ruby-inline: Does not work under Ruby 2.0

[Christian Hofstaedtler]

Just tried again with the git repository (-> 3.12.2-1), and it
appears that inline.rb needs patching for the new location of
ruby/config.h on 2.0:

ruby-inline (git)-[master] % RUBYLIB=lib irb2.0
irb(main):001:0> require 'inline'; Inline.inline :C do;end
In file included from /usr/include/ruby-2.0.0/ruby.h:33:0,
