image-oci: auto-derive IMAGE_INSTALL from OCI_LAYERS packages layers

A multi-layer image recipe (OCI_LAYER_MODE = "multi") needs every
package it puts into a packages: layer to also be reachable by
do_rootfs's recrdeptask so the package is actually built before
layer assembly tries to pull it from DEPLOY_DIR_*PK. The convention
to date has been: list each package twice — once in OCI_LAYERS, once
in IMAGE_INSTALL — and keep both in sync by hand.

Any drift between the two sources of truth silently breaks the build
at layer-assembly time. The error surfaces as "missing package in
DEPLOY_DIR" rather than as a parse-time complaint about the recipe,
so it's also annoying to debug.

The parse-time anonymous python in this class already walks
OCI_LAYERS, validates each entry, and collects every package name
into a set. It then stops at bb.debug logging that set. Append the
set to IMAGE_INSTALL instead. do_rootfs picks the entries up via the
existing recrdeptask, the recipe gets one source of truth, and drift
is no longer possible.

The append is additive — a recipe is still free to add IMAGE_INSTALL
entries that aren't named in any final layer (e.g. packages used only
during a rootfs postprocess fixup). The auto-derivation only fires
when OCI_LAYER_MODE = "multi" and at least one packages: layer is
present, so single-layer recipes and pure directories/files/host
multi-layer recipes are unaffected.
