include: kernel.mk: simplify module autoloading
Let the generic postinstall script invoke "kmodloader" when the just installed package contains any /etc/module.d/ entries. This allows us to skip the explicit "insert_module()" calls in the package postinstall. Due to the removed insert_module calls we do not need to assemble a complete list of modules per package anymore, which allows for vast simplification of the package generation code. While we're at it, also support specifying default parameters for modules using either the MODPARAM or MODPARAM.modulename variables in KernelPackage. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
