Properly resolve and use glMapBuffer / glUnmapBuffer on GLES2.
Even though we're able to resolve the function pointers, the spec says
we have to check for the GL_OES_mapbuffer extension before we use them.
Fixes a crash on a platform that doesn't advertise the extension but
still resolves the function pointers.
