tests/wayland: Add a missing "include"
From the commit message:
This avoids the following error:
../src/tests/wayland-test-clients/dma-buf-scanout.c:100:5: error:
implicit declaration of function ‘close’; did you mean ‘pclose’?
[-Werror=implicit-function-declaration]
100 | close (buffer->dmabuf_fds[i]);
| ^~~~~
| pclose
