  Turn a strcpy()+strncat()+'\0' into an equivalent snprintf().

This patch is *not* even compile tested because cross-compiling leads to
some errors like on my machine:
   cc1: error: cannot load plugin ./scripts/gcc-plugins/randomize_layout_plugin.so: ./scripts/gcc-plugins/randomize_layout_plugin.so: undefined symbol: _ZNK6frange6acceptERK14vrange_visitor

So review with care!
