Added fix for dependacy for mysql-chef_gem

Bumped the version to 0.0.4 that has a fix for ubuntu ruby191-dev.
The error this resolves is this:
```ruby
        /usr/bin/ruby1.9.1 extconf.rb
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)
        from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
        from extconf.rb:5:in `<main>'
```
