glsl: default to compat shaders in compat profile

If the shader does not specify "core" or "compatibility" in shaders
above 1.40 we were defaulting these shaders to core shaders when
in a compat profile. Instead default to compat shaders.

This brings us inline with the behaviour of the binary drivers and
fixes a crash on start-up for the game Foundation.
