On nixos, depmod is in /run/current-system/sw/bin/depmod (as a link to
/nix/store/r3r39rzsrikdsv68rvswn3hhank706gj-kmod-27/bin/depmod or
wherever the current version wants to be).
developers on guix probably face the same problem.

There is no sbin, the only things in /bin is sh, and in /usr/bin env as
I think is mandated by posix.

For their official builds they just modify the build scripts in place
before starting the build, but for dev as I keep rebasing it's annoying
to keep a couple of local patches just for this.
I could obviously manually create a link from /sbin/depmod to the
current system's but that doesn't solve the problem for all other nixos
users.

I'll send an updated patch later today..
