mesa: prevent common string formatting security issues

Adds a compile-time error for obvious security issues like:

  printf(string_var);

The proposed flag is more tolerant than -Wformat-nonliteral.
Specifically, it tolerates common mesa formatting like:

  static const char *shader_template = "really long string %d";
  printf(shader_template, uniform_number);
