build: assume snprintf() in mprintf, drop feature check

- it was already required for `curl_*printf()` float/double support.
- some curl tests always fail without it.
- it was already assumed to be present to build test servers.
  Source code did not check for `HAVE_SNPRINTF` detection variable.
- it was already required to build examples.

Windows builds stopped using this detection and the function via earlier
commits.
