avoid -Wformat-security warnings

fatal() is never called with a user-specified argument so it is safe
to pass its argument as an fprintf format string, but gcc doesn't know
that.  Use fprintf(stderr, "%s", arg) to make the intent clearer.

This fixes the build in distro setups that pass -Werror=format-security.
Based on the patch by Tormod.
