Fix QA warnings, due to using incorrect format specifiers in printf:
* contig-cmp.cc:237:50: warning: format ‘%u’ expects argument of type ‘unsigned int’,
* but argument 3 has type ‘std::vector<Contig_t>::size_type {aka long unsigned int}’ [-Wformat=]
*     fprintf (stderr, "%u b contigs\n", b . size ());
