host-tz-database: use snprintf provided by the host compiler

On certain host libc's, this prevents errors like:

  make[1]: Entering directory '/home/itk/bsp/platform-cpu20/build-host/tz-database'
  cc -DTZDIR=\"/usr/share/zoneinfo\"    -c -o zdump.o zdump.c
  zdump.c:803:1: error: static declaration of 'snprintf' follows non-static declaration
     snprintf(char *s, size_t size, char const *format, ...)
     ^
  In file included from zdump.c:23:0:
  /usr/include/stdio.h:386:12: note: previous declaration of 'snprintf' was here
     extern int snprintf (char *__restrict __s, size_t __maxlen,
                ^
  <builtin>: recipe for target 'zdump.o' failed
  make[1]: *** [zdump.o] Error 1
