Homebrew Environmental Var

[bdwyertech]

Looks like this commit got merged in and is now causing issues with the homebrew_package library.

The brew bash script now populates environmental variables which the config library is dependent upon.

Recipe: homebrew::install_formulas
  * homebrew_package[homebrew/php/composer] action install

    ================================================================================
    Error executing action `install` on resource 'homebrew_package[homebrew/php/composer]'
    ================================================================================

    TypeError
    ---------
    no implicit conversion of nil into String

Something like the following needs to be added to the homebrew_package library

  ENV['HOMEBREW_PREFIX'] = brew_cmd.stdout.chomp
  ENV['HOMEBREW_REPOSITORY'] = ENV['HOMEBREW_PREFIX']
  ENV['HOMEBREW_LIBRARY'] = ::File.join(ENV['HOMEBREW_REPOSITORY'], 'Library')
  ENV['HOMEBREW_CELLAR'] = ::File.join(ENV['HOMEBREW_PREFIX'], 'Cellar')
