emulators/vice: update to 3.9

changes: many. The full list is at http://vice-emu.sourceforge.io/NEWS .

There is a new way of screen recording which uses the ffmpeg program and
sockets, instead of the ffmpeg library, which keeps changing its API.
This may or may not work (deadlock), depending on emulator or screen settings.
Using the built-in lossless ZMBV format is a good alternative.
