Fix T68073: Wacom Intuos 5S no pen pressure on Wayland
The issue is that wayland seems to impose a generic device naming scheme
when using Xwayland For example any table stylus will show up with the
following naming convention: xwayland-stylus:33
For this to work in blender, I had to modify how the identifier string
is extracted. I also renamed the two char pointers in the search
algorithm to be more logical.
