Update license handling for pipewire recipe

We need to set LICENSE to multiple (MIT & GPL-2.0-only & LGPL-2.1-or-later) to satisfy
the current scheme required by bitbake.

But the licenses of the output packages are not all 3,
but mostly MIT and a few LGPL-2.1-or-later and one GPL-2.0-only.
To map the dynamically created output packages with the proper MIT license,
we need to call setVar after all dynamic packages are created.
