Enable unified_mode for Chef 17 compatibility

[kmkamyk]

Hello,
The behavior of unified_mode has changed in new versions of chef-client. Most of the cookbooks at supermarket.chef.io have already been adapted for this (e.g. https://supermarket.chef.io/cookbooks/yum#changelog).
Will changes be made in this cookbook ?

chef-client's logs:

The resource in the aix cookbook should declare unified_mode true at 25 locations:
