I initially committed libteken to sys/dev/syscons/teken, but now that I'm working on a console driver myself, I noticed this was not a good decision. Move it to sys/teken to make it easier for other drivers to use a terminal emulator. Also list teken.c in sys/conf/files, instead of listing it in all the files.arch files separately.
