Add lookup to create modules list from alias
We return a kmod_list when searching for an alias. Right now, it only
search for aliases in config files.
To use it, we create a list:
list = NULL;
kmod_module_new_from_lookup(..., &list);
And iterate over it to get the modules and their details:
kmod_list_foreach(l, list) {
struct kmod_mod *mod = kmod_module_get_module(l);
...
... kmod_module_get_name(mod);
... kmod_module_get_path(mod);
}
Aliases might contain globs and are match by using fnmatch().
