bitcoind: remove custom rpc user names

Simpler.
We've just removed option 'bitcoind.rpcuser', so we can also remove the
old name 'bitcoinrpc'.

netns: improve bridge setup
...
- Explain why we don't use option `networking.bridges`
- Make the bridge setup service part of NixOS' network-setup.service.
This yields no noticable functional changes for now, but it's
conceptually cleaner to finish the network setup before network.target
becomes active.
- Add 'nb-' prefix to service name

netns: remove conditionals for service settings
...
Going without the conditionals (like in secure-node.nix) adds
readability and doesn't reduce evaluation performance (in fact, it
even slightly improves performance due to implementation details
of mkIf).
To avoid errors, remove use of disabled services in secure-node.nix and
nix-bitcoin-webindex.nix.

security: simplify and fix dbus configuration
...
Previously, due to the dependency on a helper service, this dbus config
was initially inactive after system boot, allowing for unrestricted use
of the problematic dbus call.
This also broke the accompanying VM test on faster systems.
Remove 'allow' policy for root because it's a no-op:
1. It's overridden by the 'mandatory' deny policy.
2. Root can use all dbus calls anyways, regardless of policy settings.
Also, add some comments.
