Update script for OpenWrt 25

[eisengrau]

Hello,

Been using your script to build OpenWrt LXC images in Proxmox. It has worked...until now when OpenWrt 25.12 is released:

'/root/lxd-openwrt/build_dir/openwrt-sdk-25.12.0-x86-64_gcc-14.3.0_musl.Linux-x86_64//staging_dir/host/bin/opkg': No such file or directory

Would it be possible to fix?

Thank You!

Hi,

I have adapted the build script to the new package manager, apk. It should be possible to build the 25.12 rootfs now, and it boots at least in LXD.

The upgrade option doesn't work currently, and there may be other issues.
