util: fix incorrect Z bit masking in util_clear_depth_stencil()
For PIPE_FORMAT_Z24_UNORM_S8_UINT, the Z bits are in the 24
least significant bits.
Fixes http://bugs.freedesktop.org/show_bug.cgi?id=60527
and http://bugs.freedesktop.org/show_bug.cgi?id=60524
and http://bugs.freedesktop.org/show_bug.cgi?id=60047
Note: This is a candidate for the stable branches.
