server: disable DNS boostrap for SigNet nodes

Browse Source 
In this commit, we fix a bug that would cause nodes attempting to run
using the signet chain, to waste CPU as they attempted to boostrap to a
non-existent DNS seed. We fix this by ignoring the DNS boostrapper is
signet is active. Along the way, we refactor the conditional sightly to
be more readable, and easily extensible.
