[meta-ti] [RFC: PATCH 2] systemd-image: overlay local copy to enable building ti-hw-bringup-image

[Denys Dmytriyenko]

Overlay systemd-image recipe locally in meta-ti to enable building at least
ti-hw-bringup-image w/o depending on meta-angstrom.

Couple caveats:
1. Local copy sacrifices timestamp-service that is only available in Angstrom
2. It uses generic packagegroup-boot instead of angstrom-packagegroup-boot,
   which results in sacrificing angstrom-version package

With the above minor tweaks it should be possible to build ti-hw-bringup-image
w/o depending on meta-angstrom layer, only requiring meta-oe/meta-systemd...
And for anyone w/o either meta-angstrom/meta-oe/meta-systemd, it will at least
parse and not break on ti-hw-bringup-image.

On the other hand, it is still possible to get the original behavior when
using the configuration with meta-angstrom, since its original copy of
systemd-image will override the copy in meta-ti, due to higher layer priority.

Unfortunately, cloud9* images depend on additional Angstrom-specific pieces...
