lib/oe/terminal.py: declare konsole from KDE 4.x as unsupported

Konsole 2.x (from KDE 4.x) does not work as devshell - it does not pass
the environment or current working directory through among other issues,
so do a version check and disable it if it is found (skipping to the
next available terminal application.)
