swrast: Directly map the stencil buffer in read_stencil_pixels.

This avoids going through the wrapper that has to rewrite the data for
packed depth/stencil.  This isn't done in _swrast_read_stencil_span
because we don't want to map/unmap for each span.

v2: Move the unpack code to format_unpack.c.
v3: Fix signed/unsigned comparison.
