William Hubbs 73cdf10f1f Deprecate automatic loading of modules
In the hwclock, procfs and sysfs service scripts, we automatically
attempt to load the kernel modules we need before we take any action. We
shouldn't do this, because there are systems which do not use kernel
modules and do not have the kmod package installed.

With this change, we continue to load the modules ourselves, but we warn
the admin that they need to be added to /etc/conf.d/modules or built
into the kernel.

In the future, this automatic loading will be dropped.
