Adds RHEL-specific pathing

[jtreminio]

supervisord and supervisorctl are on different paths in RHEL and Debian systems.

The previous setting for path was not working:

Exec {
  path => '/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin'
}

Was getting this:

Notice: /Stage[main]/Supervisord::Pip/Exec[install_setuptools]/returns: executed successfully
default: Error: Could not find command '/usr/bin/easy_install'
default: Error: /Stage[main]/Supervisord::Pip/Exec[install_pip]/returns: change from notrun to 0 failed: Could not find command '/usr/bin/easy_install'
default: Notice: /Stage[main]/Supervisord::Pip/Exec[pip_provider_name_fix]: Dependency Exec[install_pip] has failures: true
default: Warning: /Stage[main]/Supervisord::Pip/Exec[pip_provider_name_fix]: Skipping because of failed dependencies

Setting the exec path to contain /usr/local/bin fixes issue.

I also separated the paths into array format to make it easier to see easier path.

The code in pip.pp:

exec { 'install_setuptools':
  command => "curl ${supervisord::setuptools_url} | python",
  cwd     => '/tmp',
  unless  => 'which easy_install',
  before  => Exec['install_pip']
}

Still seems to trigger the error:

Error: Could not find command 'easy_install'
Error: /Stage[main]/Supervisord::Pip/Exec[install_pip]/returns: change from notrun to 0 failed: Could not find command 'easy_install'

If I use CentOS' package manager to install python's setuptools this code works great, though.
