Pull request description:

  ### Problem

  Some functional tests are shown as skipped when running on macOS & BSD because `test_framework/netutil.py` only implemented the Linux-specific logic for checking which TCP sockets a node is listening on.

  ### Fix

  Add macOS and BSD implementations in `test/functional/test_framework/netutil.py` so tests can query:

  * which TCP sockets a node is listening on (`get_bind_addrs()`, via `lsof`)
  * a non-loopback interface address (`all_interfaces()`, via `ifconfig`)

  Then enable the previously Linux-only tests by switching to a shared POSIX platform guard.

  ### Commands
  <details>
  <summary><code>get_bind_addrs()</code> (<code>lsof</code> + regex)</summary>

  > Command used
  ```bash
  lsof -nP -a -p <pid> -iTCP -sTCP:LISTEN -Ftn
  ```

  > Flags

  - -D: device cache warnings
  - -n: no hostname resolution
  - -P: no service/port-name resolution
  - -a: AND all conditions
  - -p <pid>: filter by process ID
  - -iTCP: TCP sockets only
  - -sTCP:LISTEN: listening sockets only
  - -Ftn: machine-readable output (fields: type `t`, name `n`)

  > Regex parser

  ```regex
  t(IPv[46])\nn(\*|\[.+?]|[^:]+):(\d+)
  ```
  > Captured groups

  - group 1: IPv4 / IPv6 (used to disambiguate `*`)
  - group 2: host (`*`, `[::1]`, `127.0.0.1`, ...)
  - group 3: port
  </details>

  <details>
  <summary><code>all_interfaces()</code> (<code>ifconfig</code> + regex)</summary>

  > Command used

  ```bash
  ifconfig -au
  ```

  > Regex parsing

  Interface blocks:
  ```regex
  (?m)^(?P<iface>\S+):(?P<block>[^\n]*(?:\n[ \t]+[^\n]*)*)
  ```

  IPv4 extraction within each block:
  ```regex
  inet (\S+)
  ```
  </details>

  ### Notes

  The only remaining platform skips on macOS are the USDT/BPF tracing tests (`interface_usdt_*.py`).
