glsl: remove unecessary flags.q.subroutine_def

This bit is definitely not necessary because subroutine_list
can be used instead. This frees one more bit in the flags.q
struct which is nice because arb_bindless_texture will need
4 bits for the new layout qualifiers.

No piglit regressions found (including compiler tests) with
"-t subroutine".

v2: set the subroutine flag for validating illegal flags
