python311 vs expat

[Jonathan Perkin <jperkin%pkgsrc.org@localhost>]

This change broke both macOS and SunOS:

bac7175966909 (adam      2026-03-04 06:51:45 +0000  44) CONFIGURE_ARGS+=        --without-system-expat # requires expat_config.h

It means that python311 has both:

  CONFIGURE_ARGS+=        --with-system-expat
  CONFIGURE_ARGS+=        --without-system-expat # requires expat_config.h

I don't understand how this can work.  Does this even work on NetBSD?

I think it's clearly a regression on any other system, so if this is a 
NetBSD-specific hack then it needs to go in an .if OPSYS section, and 
I'd recommend a very good comment explaining why we have both --with and 
--without because that makes no sense to me.
