pyuno,*: kill Python 2 support with fire

Python 2 support was retained for use with --enable-python=system
on RHEL7 and SLES.  The time has arrived to remove it.

Some .py files that were imported from third parties are not changed to
enable easier replacement with updated versions if necessary.

solenv/gdb should continue to support Python 2.

bin/get-bugzilla-attachments-by-mimetype requires Python 2 to access
Launchpad.
