Backport: Fixed Erroneous HEXTILE testnovnc-legacy

The HEXTILE test which tested for a background tile followed
by an empty tile was only wide enough to actually test for one
tile, thus not actually testing the functionality.  It now actually
uses two tiles, thus actually testing the functionality.

(cherry picked from commit 4865278deead91fa58b0779b10f8e6b81d169e0e)
