Enable building image on Debian

[nekorouter]

Enable building image on Debian, since all the tools used for building image can be installed on Debian and chroot also work.

Tools dependency list has been separated and check_deps() will check this script is running on Arch or Debian, more host-distro can be supported in the future.

Thanks for the contribution!

I'm wondering if the ID variable is the best approach, since it differs for derivatives like Arch Linux ARM (ID=archarm) or Ubuntu (ID=ubuntu). Maybe using using ID_LIKE is better? Though I also don't know of the packages are always available / have the same name.

(Disclaimer: I don't know if I've ever tested the scripts on Arch Linux ARM)

Using ID from /etc/os-release may not the most complete solution, but it should be able to work on a lot of cases.
also some Arch-like distros (alarm, manjaro, cachyos) may require special handling... (e.g. alarm has no riscv64-gcc available)

(Maybe this can be improved in future, but for now I don't want to think this problem too much, so I choose using this way to handle distro detection...)

I see (and agree). Thanks again!
