[OE-core] [PATCH 1/5] image.bbclass: run postinst scripts once, at rootfs time

[Laurentiu Palcu]

This patch will allow the repeating postinst scriptlets to be run
only once, on host, at do_rootfs time. This will lower the time for
rootfs generation and, also, instead of running some time consuming
scriptlets at target's first boot, we will do on the host.
