bsd.python.mk: python3 plist shim

[Ruslan Makhmatkhanov]

Hello,

I'm planning to apply this patch to Mk/bsd.python.mk soon. It's an 
nivit's solution from devel/py-virtualenv for changes, introduced in PEP 
3147 [1]. It will not affect default packages build, because packages 
are not yet building for python3 on cluster, but it will affect python 
ports, built with python3, that already has fix like that applied 
locally. I tested it with dozen of ports and everything seems fine. 
Local fixes will be removed right after this change. Please tell me if 
there is any objections or suggestions on this. Thanks.
