Vulkan: Workaround Adreno discard bug. ( #11197 )

Always specify GLSL version 450 when compiling Vulkan shaders.
...
Bit of a risky change so late in the game but it's wrong, it needs fixing.
See for example the comments to https://github.com/hrydgard/ppsspp/commit/fb7a63bd11ba785209babfe9631956110d46c9bf
