package/libevas: quick fix to get rid of circular deps

This is a quick workaround against the recently-introduced circular
dependencies hell:

    package/xbmc/Config.in:10:error: recursive dependency detected!
    package/xbmc/Config.in:10:      symbol BR2_PACKAGE_XBMC depends on BR2_PACKAGE_HAS_OPENGL_EGL
    package/opengl/libegl/Config.in:1:      symbol BR2_PACKAGE_HAS_OPENGL_EGL is selected by BR2_PACKAGE_MESA3D_OPENGL_EGL
    package/mesa3d/Config.in:92:    symbol BR2_PACKAGE_MESA3D_OPENGL_EGL depends on BR2_PACKAGE_MESA3D
    package/mesa3d/Config.in:1:     symbol BR2_PACKAGE_MESA3D is selected by BR2_PACKAGE_LIBEVAS_GL
    package/efl/libevas/Config.in:149:      symbol BR2_PACKAGE_LIBEVAS_GL is part of choice <choice>
    package/efl/libevas/Config.in:144:      choice <choice> contains symbol <choice>
    package/efl/libevas/Config.in:144:      choice <choice> contains symbol BR2_PACKAGE_LIBEVAS_SDL_GL
    package/efl/libevas/Config.in:90:       symbol BR2_PACKAGE_LIBEVAS_SDL_GL depends on BR2_PACKAGE_SDL_X11
    package/sdl/Config.in:24:       symbol BR2_PACKAGE_SDL_X11 depends on BR2_PACKAGE_SDL
    package/sdl/Config.in:1:        symbol BR2_PACKAGE_SDL is selected by BR2_PACKAGE_PYTHON_PYGAME
    package/python-pygame/Config.in:1:      symbol BR2_PACKAGE_PYTHON_PYGAME depends on BR2_PACKAGE_PYTHON
    package/python/Config.in:1:     symbol BR2_PACKAGE_PYTHON is selected by BR2_PACKAGE_XBMC

Until this is properly fixed with the addition of a virtual package for
full-openGL providers, just depend on mesa3d instead of selecting it.
