Yarny0 59539b9bc5 tsm-client: 8.1.20.0 -> 8.1.21.0
"Update History" (release notes):
https://www.ibm.com/support/pages/node/6998343

At the time of this writing,
the "APAR" links of the "Update History" lead to 404.
However, the abstracts indicate that
this update is not security critical.

Note that this update changed the GUI window title
to "IBM Storage Protect"
(the product itself was renamed with version 8.1.19.0 already).
The commit at hand adapts the GUI vm test accordingly.

Also, all URLs in package and module comments are updated.
