mesa/subroutines: count number subroutines properly.

Browse Source 
The code was implementing the ACTIVE_SUBROUTINE_UNIFORMS
incorrectly, using the number of types not the number of
uniforms. This is different than the locations as the
locations may be sparsly allocated.

This fixes:
GL43-CTS.shader_subroutine.four_subroutines_with_two_uniforms
