glapi: fixup EXT_multisampled_render_to_texture dispatch

There's a few missing and convoluted bits:

 - FramebufferTexture2DMultisampleEXT
Missing sanity check, should be desktop="false"

 - RenderbufferStorageMultisampleEXT
Missing sanity check, is aliased to RenderbufferStorageMultisample.
Thus it's set only when desktop GL or GLES2 v3.0+, while the extension
is GLES2 2.0+.

If we flip the aliasing we'll break indirect GLX, so loosen the version
to 2.0. Not perfect, yet this is the most sane thing I could think of.

v2: [Emil] Fixup RenderbufferStorageMultisampleEXT, commmit message
