egl: Replace KHR_surfaceless_* extensions with KHR_surfaceless_context

KHR extension name is reserved for Khronos ratified extensions, and there is
no such thing as EGL_KHR_surfaceless_{gles1,gles2,opengl}.  Replace these
three extensions with EGL_KHR_surfaceless_context since that extension
actually exists.
