tcg/i386: fix unsigned vector saturating arithmetic

Browse source 
Due to a cut/paste error in the original implementation, the unsigned
vector saturating arithmetic was erroneously being calculated as signed
vector saturating arithmetic.

Fixes: 8ffafbcec2 ("tcg/i386: Implement vector saturating arithmetic")

Backports commit 3115584d39afe8cf2a84a40549029f53792abca5 from qemu
