bitbake offers a choice of DEB, RPM or IPK packaging. To a degree the
choice is functionally arbitrary for image generation but control over
the package format becomes important if we want to:
1. Include runtime package management functionality in the firmware image
2. Mess about with the packages on the build system
With respect to 1 the IPK format and opkg (an ipk package manager) are
designed for embedded systems[1] - by contrast to RPMs have heavier
dependencies and a greater impact on the size and complexity of the
firmware image.
Regarding 2, the embedded nature and the need for opkg to work without
much fuss leads to a lower configuration barrier by comparison to RPMs.
With ipk it becomes possible to reuse the packages built during image
preparation for core analysis without needing to generate an SDK:

This approach documented in the Poky Reference Manual:
https://www.yoctoproject.org/docs/1.0/poky-ref-manual/poky-ref-manual.html#platdev-gdb-remotedebug-launch-gdb-inferiorbins
Switch all machines to IPK to align the debugging experience with
upstream's documentation and to facilitate efficient use of packaged
software at runtime.

Upstream bbclasses changed to typically use the `:${PN}` override
syntax, including the SYSTEMD_ variables. Change our systemd.bbclass
to do the same for consistency and perform a tree-wide variable
replacement.
Spot checked by building bletchley and witherspoon and checking
some of the SYSTEMD_LINK directives on installed packages under qemu.

HXTBASE is only used for pointing at licenses...point at the
licenses in oe-core in meta/files/common-licenses instead. to match the
defacto convention used in other oe layers like meta-openembedded.
