Cookbook disables root account

[jblaine]

There are specific cases where clamd needs to run as root. Setting default['clamav']['user'] = 'root' to get the desired results ends up locking out the root account because of this code in recipes/users.rb:

user node['clamav']['user'] do
  comment 'Clam Anti Virus Checker'
  system true
  shell '/sbin/nologin'
end

Please at least consider a guard of not_if { node['clamav']['user'] == 'root' }
