Buildfarm setup for AIX

Hi Team,

Here are few updates on the buildfarm setup for AIX.
We got a latest Power9 node in OSU lab dedicated for Postgres community
development activity.

In the last couple of weeks, we have setup the buildfarm on a node in OSU
lab for all the supported versions of Postgres on AIX(13/14/15/16).

https://buildfarm.postgresql.org/cgi-bin/show_history.pl?nm=douc&br=REL_13_STABLE
https://buildfarm.postgresql.org/cgi-bin/show_history.pl?nm=douc&br=REL_14_STABLE
https://buildfarm.postgresql.org/cgi-bin/show_history.pl?nm=douc&br=REL_15_STABLE
https://buildfarm.postgresql.org/cgi-bin/show_history.pl?nm=douc&br=REL_16_STABLE

For other latest releases(17/18/master) we are planning to run them locally
on our node.

Currently we are seeing some issues in the TAP test for REL_16.

Non-zero exit status: 2
Parse errors: No plan found in TAP output

These tests were passing on other buildfarms (animals) , trying to debug if
there are any environment specific issues.
