mesa: fix RGBA_SIGNED_COMPONENTS for lowered signed luminance

Browse Source 
Some drivers implement luminance as RGBA. Since the code checks the
renderbuffer format instead of the internal format this can cause the
query to incorrectly return "signed" on the Alpha component for signed
luminance formats.

Fixes the following Piglit test for various drivers (at least Panfrost
and V3D):
