main/util-linux: fix license information

Currently, we throw a very wide license-net. The truth is however, that each utility/library has its own license, and using the big license-net doesn't really help here.

Instead, lets narrow things down and explicitly set the licenses to the components.

Note, that the general rule from util-linux repo applies, 'utilities without their explicit licensing mentioned, are GPL-2.0-or-later.

While here, add a few missing discovered licenses to our wide-net, but without going over each individual file, this is probably still not complete.
