While Haiku usually brings Python with it so its license is available
in the merged licenses directory, this isn't declared as a dependency
anywhere and therefore "chance". Since we yet lack a way to declare this
dependency (for lack of a license entity), duplicate the Python license
in the ports requiring it to make them self-contained.
* Referring the current haiku version explicitly is not needed, since
the RequiresUpdater takes care of setting the version of Haiku used
for building a package.
* portVersionedName contains the secondary architecture,
so using it means secondary package builds fail.
example: $portVersionedName is libwow_x86-0.0.0 when
doing an x86 build on x86_gcc2
