fix(26.04): util-linux no longer needs liblastlog

[cjdcordeiro]

Proposed changes

Removed unneeded dependency from util-linux_login.

IMPORTANT NOTE: this is an interesting case where the opening of a new release carried a change that cause orphaned dependencies. In #662, @lengau introduced a missing dependency to util-linux, that was needed for the lslogins binary.

In 26.04, that binary is no longer in the pkg and consequently no longer in the util-linux_login slice. However, the liblastlog2-2 is left over from #662, and is getting unnecessarily installed. That's not good, cause it goes against what we try to do with Chisel -> remove everything that is unnecessary

I noticed this because liblastlog2-2 brings in sqlite3 libs too, which completely caught me off guard.

So what's the takeaway? We're doing a good job at detecting and testing dependencies that are missing, and we don't do enough checks to ensure that we are not shipping unnecessary. lslogins was removed in https://github.com/canonical/chisel-releases/pull/857/changes#diff-19d63239e73ac43045433aa7c62758e215be4782ad63accaec2435ddaf8254d0L156. The CI that list the dependency diff did NOT run in #857, unfortunately. That would have (hopefully) said that there was an unnecessary dependency. BUT, even with that, it would have just been an informative comment, while IMO this should've been a CI error. @lczyk can you pls ACK, weigh in, and if agreeing, create a candidate roadmap item for us to tackle this in future releases?
