weston: check for both EGL and GLES

The conditional is wrong, it was check for BR2_PACKAGE_MESA3D_OPENGL_ES
(correct, means GLESv2 support) and BR2_PACKAGE_MESA3D_OPENGL_GLES
(incorrect, there's no such symbol).
So now check for BR2_PACKAGE_MESA3D_OPENGL_EGL (EGL support) plus
BR2_PACKAGE_MESA3D_OPENGL_ES (GLESv2 support), both are required.
