[PATCH] rootfs: support default package list extension

[Ivan Nikolaenko <ivan.nikolaenko@unikie.com>]

This patch will allow users to add their packages to the
Spectrum OS rootfs.

To do so, the user needs to declare a variable "additionalPackages"
in his overlay with the list of required packages.

Please, note that static packages need to be taken from
pkgsStatic list, since additionalPackages are added from pkgs list.
