remove trailing commas at the end of hash

this restores compatibility with ruby 1.8

@chr4 thank you for the PR. This cookbook requires Ruby 1.9 or higher, as documented in the README. If you want 1.8 support, you'll need to use a version in the 1.0.x series. Opscode's omnibus installer uses Ruby 1.9.3, and Ruby 1.8 has been officially deprecated.

srsly? Two commas for the cost of breaking compatibility?
Please don't make me maintain a fork for the sake of 2 bytes...

@chr4 there are additional incompatibilities that arise in the File class and other places as well. You can use an older version of the cookbook that has 1.8.7 compatibility - I follow semver in this cookbook. Those trailing commas are encouraged by multiple git/ruby style guides, as it improves the readability of git diffs. You don't need to maintain a fork - either use Opscode's omnibus installer (which has a compatible version of Ruby) or use the 1.0.x series of the cookbook.
