packagegroup-core-tools-profile: don't exclude mips

Now that liburcu supports mips, this packagegroup can pull in lttng recipes
(lttng-ust, lttng-tools, lttng-modules, babeltrace) on that architecture as it
does for the others.

avahi: inherit python classes, use PACKAGECONFIG

Without using our python classes and having appropriate dependencies, the
build is nondeterministic, and whether a python-avahi package is produced will
vary depending on the host environment, yet avahi-discover is always produced,
and it depends on python-avahi.

license.bbclass: include all licenses in the manifest

When we don't have a generic license file for the license in question, we can
warn, but we should still include it in the manifest, otherwise the manifest
doesn't reflect reality. Failing to include a license listed in the recipe in
the manifest can't be allowed.
