check_deptypes in port_binary_distributable.tcl

[Christoph Iserlohn]

I was wondering why the port_binary_distributable.tcl script checks the
licenses for depends_build/depends_lib instead
of depends_lib/depends_run dependencies? Non-distributable or
confliciting licenses in build time dependencies should
not affect the distributability of a port contrary to
non-distributable/conflicting licenses in run-time dependencies.
