lang/tcl: install modules like upstream wants, fixing pkg/56696

We carried a patch that changed the installation of the standard Tcl modules,
to some old style with names that apparently made PLIST generation easier.
Now, we got some more fixed version numbers that will change on updates,
but the upside is that R does not enter an endless loop anymore on installing
R-tcltk2 when DISPLAY is empty, see pkg/56696, which should be fixed now.

Take care with PLIST when updating and please don't re-introduce the bug.
A better fix might be to fix the endless loop in Tcl as called by R, but
just messing around with upstream installation is not a good starting
point.
