linker: Fix consumer_inputs_with_locations indexing

In an earlier incarnation of populate_consumer_input_sets and
get_matching_input, the consumer_inputs_with_locations array was indexed
using the user-specified location.  In that version, only user-defined
varyings were included in the array.

In the current incarnation, the Mesa location is used to index the
array, and built-in varyings are included.

This change fixes the unit test to exepect gl_ClipDistance in the array,
and it resizes the arrays to actually be big enough.  It's just dumb
luck that the existing piglit tests use small enough locations to not
stomp the stack. :(
