[Mesa-dev] [PATCH v2] main: fix basename match's check if it's an array or struct

[Samuel Iglesias Gonsalvez]

Commit 4565b6f did not update the basename match's check for
the case that string would exactly match the name of the
variable if the suffix "[0]" were appended to it.

Fixes two dEQP-GLES31 tests:

dEQP-GLES31.functional.program_interface_query.shader_storage_block.resource_list.block_array
dEQP-GLES31.functional.program_interface_query.shader_storage_block.resource_list.block_array_single_element

v2:
- Change the position of rname_has_array_index_zero to avoid an out-of-bounds
  read. Reported by Tapani Pälli.
