bitbake: Use IPK packaging for rootfs assembly

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:

```
$ export LD_LIBRARY_PATH=./tmp/work/x86_64-linux/opkg-native/*/recipe-sysroot-native/usr/lib
$ MY_DEBUG_ROOT=tmp/rootfs-debug
$ ./tmp/sysroots-components/x86_64/opkg-native/usr/bin/opkg \

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.
