Fix build with loadThemeCursor templates
WaylandCursorImage::loadThemeCursor(const T &shape) uses templates. These templates are used by input.cpp but the deifnition is in pointer_input.cpp
On some setups this creates a compilation problem.
This patch introduces an explicit non-templated declaration with the defintion explicitly complied into the same class.
In master this has been refactored away anyway, so this is a minimal patch to make things work in the least invasive way.
