The now preferred way to call realpath() is by passing NULL as the

old way of providing our own buffer as a second argument, for some
platforms that didn't support the new way yet. Those were only
Solaris less than version 11 and some older AIX versions (7.1 and
newer appear to support the new variant). We don't support those
platforms versions anymore, so we can remove this extra code.
I checked this in the AIX 7.3 manual and the POSIX 2008 way does not
appear to be mentioned there:
https://www.ibm.com/docs/en/aix/7.3?topic=r-realpath-subroutine
That's a bit confusing, or maybe there are just too many versioning
systems to keep track of and I've made a mistake, because it looks
like AIX 7.2.5+ has actual certification for Unix V7 AKA SUSv4 AKA
POSIX 2008... Or maybe the documentation is wrong and it does
actually work. I guess the IBM crew will be forced to look into this
as they continue to work on their PostgreSQL/AIX patch, if it doesn't
work...
Tom had tested this on and found that it does actually work on AIX 7.1
and 7.3 but the documentation is wrong.
