util: Only use open coded snprintf for MSVC.

MinGW has snprintf.

The patch fixes these warnings with the MinGW SCons build.

src/gallium/auxiliary/util/u_snprintf.c:459:1: warning: no previous prototype for ‘util_vsnprintf’ [-Wmissing-prototypes]
src/gallium/auxiliary/util/u_snprintf.c:1436:1: warning: no previous prototype for ‘util_snprintf’ [-Wmissing-prototypes]
