st/mesa: fix SINT <-> UINT conversion during PBO upload / download

This fixes use cases like glReadPixels from an RGBA8I framebuffer into
a PBO with type GL_INT by clamping values appropriately when they fall
outside the range of the destination format.

Fixes parts of GL45-CTS.gtf32.GL3Tests.packed_pixels.packed_pixels_pbo.
