clients: avoid build error without gl-renderer

Make sure gl-renderer is enabled when building the EGL and EGL
dmabuf clients. This avoids missing declaration warnings and
linking errors such as:
  ../clients/simple-dmabuf-egl.c:1142: undefined reference to `weston_check_egl_extension
  ...
  ../clients/simple-egl.c:206: undefined reference to `weston_check_egl_extension'
