st/mesa: Prefer 5551 formats for GL_UNSIGNED_SHORT_5_5_5_1.

Previously, internalformat GL_RGBA and type GL_UNSIGNED_SHORT_5_5_5_1
was promoted to RGBA8888 as the table entry with the 5551 formats
is listed below the 8888 entry, and it also doesn't have GL_RGBA as
a possible internalformat.

Using actual 5551 fixes the following dEQP-EGL test:
- dEQP-EGL.functional.image.modify.tex_rgb5_a1_tex_subimage_rgba8
