Bill Currie 3da90b612f [vulkan] Remove superfluous glyph fragment shader 
The main reason I had created in the first place was I hadn't thought of
using image view swizzles to handle coverage-alpha textures (for
monochrome glyphs), and for whatever reason also had the texture in a
different binding slot to the twod fragment shader. With both issues out
of the way, there's no reason to have an almost identical (just some
naming) shader just for glyphs.
