Clément Chigot 53c9c06811 misc/cgo: enable testso and testsovar on aix/ppc64
On AIX, shared objects must be wrapped under an archive file.

For testso, creating libcgosotest with an extern symbol isn't
AIX-friendly. By default, ld will block such behavior. Rather than
forcing ld to work as on Linux and using the run-time linking,
goCallback became a function pointer which is set by setCallback().

Updates #30565
