modprobe error while building iscsi container

[Christian Berendt]

I do not use the iscsi container and do not know if this is an issue not. When building the iscsi container I got the following error message:

INFO:kolla.image.build:iscsid:modprobe: ERROR: ../libkmod/libkmod.c:556 kmod_search_moddep() could not open moddep file '/lib/modules/4.4.0-22-generic/modules.dep.bin'

The following will solve the issue:

load the kernel module configs
start the service sys-kernel-config.mount on ubuntu
