glsl: use correct shader source in case of cache fallback

The scenario is:

glShaderSource
glCompileShader <-- deferred due to cache hit of shader

glShaderSource <-- with new source code

glAttachShader
glLinkProgram <-- no cache hit for program

At this point we need to compile the original source when we
fallback.
