[PATCH] selftest: Test installation of recipes with complex packaging

[Paul Barker <paul@pbarker.dev>]

When recipes have complex and dynamic packaging, it's easy to
accidentally end up with one or more packages that build but can't be
installed. We've seen this recently with linux-firmware [1].

Skimming through the recipes that set PACKAGESPLITFUNCS or
PACKAGES_DYNAMIC or are otherwise known offenders, I've also picked out
gstreamer1.0-plugins-*, kernel-modules, perl and python3 as recipes
where it would be easy to end up with similar issues in the future.
