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

bitcoind: clarify how bitcoin-cli RPC access is enabled
It's not immediately clear why rpcuser/rpcpassword are needed in addition to the rpcauth
config entries.

bitcoind: move rpc user config to bitcoind
This enables modules-only usage.
The privileged user is needed by bitcoind (cli), the public user is
needed by other services.

bitcoind: add rpc user option 'passwordHMACFromFile'

user-specific code in preStart.

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: rename bridge peer devices br-nb-veth* -> nb-veth-br*
This ensures a consistent 'nb-' namespace and simplifies the
dhcpcd.denyInterfaces rules.

Also rename vethName -> veth.

netns: rename bridge br0 -> nb-br
br0 has a high risk of name clashes when nix-bitcoin used as part of a
larger config.
Use a more specific 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.

netns: remove redundant filter
The 'availableNetns' connection matrix only consists of enabled entries,
so no extra filtering is needed.
Reason: availableNetns starts with the filtered 'base' and is then symmetrised.

security: enable full systemd-status for group 'proc'
Previously, systemd-status was broken for all users except root.

Use a 'default' deny policy, which is overridden for group 'proc'.

Add operator to group 'proc'.

Also, remove redundant XML boilerplate.

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.
