Move check_resolver_bins again, handle double CN

When running in debugging mode, HAS_DIG and friends was
still false as check_resolver_bins() was called too late.
This amends basically bac0f66112 .

In cases where a certificate has two CNs, the output contained
a linefeed. This replaces the line feed by a space.
