meta: fix GetTexImage() for luminance, l/a, intensity formats
The GL spec says that luminance values are returned as (l, 0, 0, 1),
L/A values as (l, 0, 0, a) and intensity values as (i, 0, 0, 1).
Use the pixel transfer scale controls to implement that.
This fixes a few failures in the new piglit getteximage-formats
test when getting a compressed L or L/A image.
