Superseded patch for Tcl::Tk t/text.t

[Christopher Chavez]

A few days ago, I noticed how text.t would be skipped due to "no tklib 
extension available" even if tklib was installed. I found that changing 
`pkg_require('scrolledwindow')` to `pkg_require('widget::scrolledwindow')` got 
it working.

I had come up with the following patch and was about to open a pull request, 
but then 1.12 was released with snit included, so the very test for 
scrolledwindow I had patched was removed.

Just sending this along for reference.
