workstation: Patch XTerm to set $COLORTERM

While ncurses already has support for detecting direct color terminals,
a lot of applications out there do not yet query terminfo but instead
rely on some shady COLORTERM environment variable. While I don't really
like that approach, patching XTerm to set that variable currently is
better than patching all the applications to query terminfo.
