[OE-core] [PATCH V3 1/2] initscripts: split the functions script into a separate package

[Chen Qi]

Many SysV init scripts need the /etc/init.d/functions script. But
this script is part of the initscripts package. As a result, the
initscripts package should always be installed into the system to
avoid errors when starting daemons. However, it makes no sense to
install the initscripts package into a systemd based image, because
what the init scripts provide has already been provided by the systemd.
On the other hand, the functions script might be still needed in a
systemd based image because other init scripts such as distcc might need
it.

The above situation leads to a natural separation of the functions script
from the initscripts package. And this patch does so. It separates the
functions script into initscripts-functions packages.
