[OE-core] [PATCH 1/2] image.bbclass: allow override for ROOTFS_BOOTSTRAP_INSTALL

[Qi.Chen at windriver.com]

From: Chen Qi <Qi.Chen at windriver.com>

Previously, if 'package-management' is in IMAGE_FEATURES, this variable
is set to "", otherwise, it's ${ROOTFS_PKGMANAGE_BOOTSTRAP}. It works fine
with deb and ipk, because their postinsts rely on their package managers.
However, rpm is a little different, as its postinsts are just shell scripts.

We should allow rootfs_rpm.bbclass to override this variable, otherwise,
rpm-postinsts will not be installed on target if 'package-management' is
in IMAGE_FEATURES.
