fix: crash on WireGuard profiles with empty remote DNS (#6379)

Browse Source 
When a WireGuard profile has no remote DNS, CoreOutboundBuilder fell
back to listOf(WIREGUARD_LOCAL_REMOTE_DNS). The constant is a single
comma-separated string, so the core received one list element holding
all four addresses and panicked on start:

  panic: ParseAddr("1.1.1.1,1.0.0.1,2606:4700:4700::1111,..."):
  unexpected character

closes: #6373
