[Piglit] [PATCH 15/21] arb_internalformat_query2: add generic check for GET_TEXTURE_IMAGE_TYPE

[Alejandro Piñeiro]

>From spec:
 "GET_TEXTURE_IMAGE_TYPE:
  <skip>

  Possible values include any value that is legal to pass for the
  <type> parameter to GetTexImage, or NONE if the resource does not
  support this operation, or if GetTexImage is not supported."

Tested on NVIDIA GeForce GTX 950 - NVIDIA 352.55: pass.
