mesa: allow GL_UNSIGNED_BYTE type for SNORM reads
OpenGL ES spec states:
"For normalized fixed-point rendering surfaces, the combination format
RGBA and type UNSIGNED_BYTE is accepted."
This fixes following failing VK-GL-CTS tests:
KHR-GLES3.packed_pixels.pbo_rectangle.rgba8_snorm
KHR-GLES3.packed_pixels.rectangle.rgba8_snorm
KHR-GLES3.packed_pixels.varied_rectangle.rgba8_snorm
