[perl #41808] [PATCH 1/6] [library] Test::More: use hllmacros.pir in man page example

[Allison Randal via RT]

Namespaces have an export feature. A bit clunky, but a definite
improvement over the .IMPORT macro. I've replaced all instances of
.IMPORT with the "export_to" method, except
languages/PIR/examples/test.pir, because it seems to just be a generic
syntax example.
