rc.d: add a service jails config to all base system services

This gives more permissions to services (e.g. network access to
services which require this) when they are started as an automatic
service jail.

The sshd patch is important for the sshd-related functionality as
described in the man-page in the service jails part.

The location of the added env vars is supposed to allow overriding them
in rc.conf, and to hard-disable the use of svcj for some parts where it
doesn't make sense or will not work.

Only a subset of all of the services are fully tested (I'm running this
since more than a year with various services started as service jails).
The untested parts should be most of the time ok, in some edge-cases
more permissions are needed inside the service jail.

rc.d/hostid: Skip warning on systems w/o smbios

The first time a FreeBSD system boots, it obtains a hostuuid and hostid
from the smbios.system.uuid kernel environment variable. If this value
is found to be invalid, a warning is printed and the boot pauses for
two seconds to give the user a chance to read it.

If the FreeBSD kernel is launched directly in a virtual machine rather
than via the FreeBSD boot loader, the smbios.system.uuid environment
variable might not be set; in this case, there's no need to alert the
user and delay the boot process since the lack of a "hardware" uuid is
entirely expected.

Distinguish between the cases of "invalid UUID" and "no UUID", warning
and delaying the boot only in the former case. In both cases we still
generate a random UUID in software.

No functional change intended.

I adjusted the commit message and did some final clean-ups of the patch

Move the rc framework out of sbin/init into libexec/rc.

The reasons for this are forward looking to pkgbase:
* /sbin/init is a special binary; try not to replace it with
every package update because an rc script was touched.
(a follow-up commit will make init its own package)
* having rc in its own place will allow more easy replacement
of the rc framework with alternatives, such as openrc.
