(PE-12002) Add AIX support

This change adds puppet agent support for AIX.

Support is gated by the 'aix' operatingsystem fact
and an archetecture fact matching 'PowerPC_POWER[5,6,7]'.

This change uses the same strategy as sles for removing
unused packages as aix doesn't have fully fledged package
management for rpms.
