[PATCH] cairo-wideint: Fix typo in two cairo_uint128 functions

_cairo_int128_negate and _cairo_int128_not are #defines of
_cairo_uint128_negate and _cairo_uint128_not respectively.  The function
implementations should use the actual function name not the aliases.  On
systems without a uint128 type, these could lead to build issues.

Credit for finding this go to Dr. Peter Barnes, LLNL.
