#1176: varnishd segfaults if no storage backend has been defined

 If you start varnishd by e.g. '-s Transient=malloc' as the only storage
 declaration, it will start without any storage backends defined. When it
 tries to allocate storage, it will segfault.

 This is because the -s option correctly makes varnishd skip the default
 storage backend declaration. When that -s option only redefines the
 transient storage, there still aren't any non-transient storage backends
 defined.
