Copy a random selection of 'count' router infos from configDir/netDb
to 'toDir'. Skip your own router info, and old, hidden, unreachable, and
introduced routers, and those from bad countries.
Much easier than the one in installer/tools since we have a running router.
Caller must delete file when done.
Since:
0.9.19 modified from BundleRouterInfos in installer/tools
Create a zip file with
a random selection of 'count' router infos from configDir/netDb
