This actually fixes a bug in current unit - which can trigger cycle issues in some situations

I thought it best to keep this in-line within the package to simplify install. Am happy to move this separately

It works fine without the bash completion. But it's much nicer with it.

Belt and suspenders approach needed here since we are no-longer using a top-level glob
Replace ConnMan with rxnm v1.1.1 and systemd-networkd for network management: - rxnm handles L3 operations (DHCP, routing) via systemd-networkd - IWD operates in L2-only mode for WiFi authentication - networkd templates auto-configure all interface types - Eliminates ConnMan's 7MB daemon and dependencies (glib, ncurses, readline) rxnm.service extracted to system.d/ directory following ROCKNIX packaging convention. TimeoutStopSec=1s added to rxnm.service and systemd-networkd (via drop-in override) to align with systemd aggressive shutdown policy. Validated: RK3566 across multiple boot cycles (WiFi WPA3, USB hotplug, AP mode, routing, DNS via systemd-resolved). make world passes all targets.

Nothing rxnm code related - just some packaging tweaks.

Replace ConnMan with rxnm v1.1.1 + systemd-networkd as the network management stack. This is a minimal introduction for full replacement — all user and low-level networking functionality works exactly as it does pre-rxnm (and in several cases, better).
rxnm delegates L3 (DHCP, addressing, routing) to systemd-networkd and keeps IWD in L2-only mode for WiFi authentication. Standard networkd .network templates handle all interface types — WiFi station, ethernet, USB gadget, Bluetooth PAN, AP/hotspot — automatically via template matching, without user interaction. Zero-touch unless the user wants to customize, in which case it is standard networkd config overrides.
This eliminates ConnMan's 7MB daemon and glib/ncurses/readline deps, replacing them with ~150KB of shell libraries and a 50KB native C agent. Measured on RK3566 hardware: 7.8 MiB RSS saved, 5 MiB less system memory used, 23 fewer CPU jiffies at idle — lighter across every dimension.
Changes:
Hardware validated on RK3566 across multiple boot cycles: WiFi station (WPA3), USB ethernet hotplug, local-play AP mode, dual-homed routing, profile save/load, DNS via systemd-resolved, nullify enable/disable. EmulationStation WiFi UI works unchanged — no ES modifications needed.
make world passes for all 9 targets (RK3588, RK3566, RK3326, RK3399, S922X, SM8250, SM8550, H700, SM8650).
Note: XDP/eBPF kernel module support for nullify power management modes will come in a separate patchset. This change focuses solely on the ConnMan-to-rxnm network stack replacement.
