📄 Description

What

Make wg-quick's Android integration prefer the amneziawg kernel module over the userspace amneziawg-go binary for configurations that use AWG obfuscation parameters.

Why

add_if() previously routed any config containing AmneziaWG parameters (Jc, Jmin, Jmax, S1-S4, H1-H4, I1-I5) to the userspace amneziawg-go binary, even when the kernel module is present. Since amneziawg-go is not shipped with the Android app, kernel-mode tunnels with AWG obfuscation failed with amneziawg-go: inaccessible or not found (exit 127).

The kernel module supports all these parameters via awg setconf, so the selection is now kernel-first:

use ip link add ... type amneziawg whenever /sys/module/amneziawg is available;
keep amneziawg-go only as a fallback for devices without the kernel module.

Drops the now-unused is_awg_on flag and the parser branches that only existed to set it.

Testing performed

Built wg-quick for Android target.
Pushed to device (Xiaomi 11 Lite 5 NE, kernel 5.4.302 QGKI with amneziawg kernel module 3.0.20260805), kernel-mode tunnel with obfuscation (Jc/Jmin) connects successfully and gets a handshake.
wg-quick up / wg-quick down cycle verified in both kernel-module and userspace-fallback modes.
