[gentoo-dev] [PATCH] kernel-install.eclass: run depmod after compressing modules

[Andrew Ammerlaan <andrewammerlaan@gentoo.org>]

(de)compressing modules changes the path of the module files so we need to
run depmod to ensure that tools such as modprobe/modinfo work.

Note that depmod is often, but *not* always, run by sys-kernel/installkernel.
Systemd installs a hook to do this, but there is no equivalent on openrc
systems. So instead just ensure that the tree of modules we install is
consistent here in the eclass.
