LICENSE=, RESTRICTED=, set NO_*_ON_*.

The license is only available as a pdf, and I decline to extract and
check in text.

This license is clearly non-Free, and no permission is granted to
distribute source or binaries, so set NO_*_ON_*.

Fixes PR pkg/43210.
Add LICENSE=, set NO_*_ON_*.

The licensing for this package is unclear.  In particular, it appears
to contain an embedded copy of pdflib.  Mark it non-redistributable
until someone analyzes and addresses the issues.
