[OE-core] [PATCH 1/1] rootfs.py: Change logic to unistall packages

[mariano.lopez at linux.intel.com]

From: Mariano Lopez <mariano.lopez at linux.intel.com>

In the current state some of the base utils (update-rc.d,
base-passwd, shadow, and update-alternatives) are unistalled
when there is no package manager in the image. Checking for
previous commits, the unistall of these utils were to be
done in a read-only filesystem.

It is a valid option to have these utils without a package
manager, and also make sense to remove them when building a
read-only filesystem.

This changes the check logic from having a package mananger
to if is a read-only filesystem to remove the utils.

Another change implemented with this patch is that delayed
post installs now doesn't depend if there is a package manager.
Also it is a valid option to have post install scripts without
package manger.
