python3: refresh LICENSE information

Changed PKG_LICENSE to reflect spdx license tag, and PKG_LICENSE_FILES
to include all lincense-related files applicable to the parts of the
code we are actually using to build and/or distributing.  The
Windows-only files, and the python-bundled Tools we're not using have
been left out.
