selftest: Test installation of recipes with complex packaging

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.
