mesa: Fix missing GLES3 headers in SDK sysroot

Building weston with core-image-weston SDK fails:
```
../libweston/renderer-gl/gl-shader-config-color-transformation.c:29:10: fatal error: GLES3/gl3.h: No such file or directory
   29 | #include <GLES3/gl3.h>
      |          ^~~~~~~~~~~~~
```

Both GLES2 and GLES3 implementations are contained in libGLESv2.so.2,
which is packaged in libgles2-mesa. However, the headers are split
between libgles2-mesa-dev and libgles3-mesa-dev, which is why the
GLES3 headers end up missing in the SDK sysroot.

Add a dependency so the GLES3 headers are properly associated with
the GLES3 implementation.
