Log:
  Allow USES=go ports to override make targets & include <bsd.port.pre.mk>
  
  Prior to this change, if a port had:
  - USES=go.mk,
  - .include <bsd.port.pre.mk>, and
  - overrode a make target (e.g. post-extract:)
  
  then the following warnings were produced when invoking make on the port:
    make: "/usr/local/poudriere/ports/default/CATEGORY/PORT/Makefile" line XX: warning: duplicate script for target "post-extract" ignored
    make: "/usr/local/poudriere/ports/default/Mk/Uses/go.mk" line 68: warning: using previous script for "post-extract" defined here
  
  This change fixes this issue by wrapping the definition of make targets
  in a separate once-only !defined wrapper which is blocked until post.mk.
  This concept was copied from Mk/Uses/python.mk.
