util-linux: Improve the package licenses

The default license for util-linux is GPL-2.0-or-later.

Most of the applications and the libraries are also linked with
libcommon.la, which uses these licenses:
LGPL-2.1-or-later & BSD-2-Clause & BSD-3-Clause & MIT

Set the above licenses for all dynamic packages, unless explicitly
specified.

In particular, this avoids setting BSD-4-Clause-UC and EUPL-1.2 on
packages where they do not belong.
