glsl: use linked_shaders bitmask to iterate stages for subroutine fields
This should be faster than looping over every stage and null checking, but will also make the code a bit cleaner when we switch to getting more fields from gl_program rather than from gl_linked_shader as we can just copy the pointer and not need to worry about null checking then copying.
