Comment 1 for bug 1833586

After discussing with Ryan on IRC:

 - the static loading of the modules is bad, and shouldn't be necessary, as it should be possible to figure out at runtime which transports are actually needed by iscsid
 - the current implementation doesn't work in the initramfs at all since the file it creates is only read by systemd
 - upstream's code has support for loading these modules on-demand, *IF* we link against libkmod.

Proposed solution:

 - Build-depend on libkmod-dev
 - Drop the file for loading modules statically
 - Add ib_iser to the list of modules for the initramfs hook, so that iscsi rootfs will work correctly over infiniband as well
