Need AIX OS support on ppc64

[ritvick]

Hi,

Currently, this plugin does not support AIX OS. This issue is to add that support. On an AIX host using any of the task and features of this plugin result in "Unsupported OS: AIX".

Hi @ritvick thanks for the PR, it looks good from my end but I don't have access to an AIX host so I can't verify it
But 7.1.0 has been released with your changes

Thank you, we will verify and let the community know here.
