Include array index in reflected uniform names more consistently

* This comes from the resolution of issues 4, 5 & 6 in
  ARB_program_interface_query, stating that uniform buffers should have their
  members expanded out as normal and arrays should have elements added.
* If a buffer block has a large array e.g. [10000] we don't want to iterate over
  every array element. Instead we should only expand out the first [0] element,
  then expand as normal from there.
* The array name should still be appended with [0] to indicate that it's an
  array.
