Ok, I think this is a broken setup that has a separate /sbin but does
not have it in the PATH.

As you noticed, you can fix it with

   DEPMOD=/sbin/depmod

or you could just make /sbin part of your PATH.

It looks like on your distro, /sbin is restricted to just the
super-user PATH, which is odd, but I guess there's at least _some_
logic to it.

I guess we could have some compatibility thing in scripts/depmod.sh,
something like

  diff --git a/scripts/depmod.sh b/scripts/depmod.sh
  index e083bcae343f..a93261207453 100755
  --- a/scripts/depmod.sh
  +++ b/scripts/depmod.sh
  @@ -15,6 +15,8 @@ if ! test -r System.map ; then
        exit 0
   fi

  +# legacy behavior: "depmod" in /sbin
  +PATH="$PATH:/sbin"
   if [ -z $(command -v $DEPMOD) ]; then
        echo "Warning: 'make modules_install' requires $DEPMOD. Please
install it." >&2
        echo "This is probably in the kmod package." >&2

or similar. Does that work for you?
