[PATCH wayland 1/2] tests: C++ compilation test

[Mariusz Ceier]

This test includes one of wayland headers, which produced
error with C++ compiler. C compiler can't be used for this test,
because it issues only a warning[1] and only when wayland headers
are not installed in system headers path (/usr/include).

[1] wayland-server-protocol.h:201:2: warning: implicit declaration of function ‘wl_resource_post_event’
