st_glsl_to_tgsi: only skip over slots of an input array that are present

Browse source 
When an application declares varying arrays but does not actually do any
indirect indexing, some array indices may end up unused in the consuming
shader, so the number of input slots that correspond to the array ends
up less than the array_size.
