Improve linking of test/cairo_test.cxx demo program 

With modern CMake libcairo doesn't need to linked explicitly in the
test/cairo_test.cxx demo program. Either '-lcairo' is implied by
linking with fltk::fltk or it is not used at all.

This fixes a linker warning on macOS:
  "ld: warning: ignoring duplicate libraries ..."
