Verbose DNF5 logs in Fedora Copr

[praiskup]

So far I deployed package_manager=dnf5 release only on our staging instance. But the DNF5 logs there are pretty ugly, snippet:

Installing groups:                                                                   
 Buildsystem building group                                                          

Transaction Summary:
 Installing:      152 packages

Total size of inbound packages is 52 MiB. Need to download 52 MiB.
After this operation 180 MiB will be used (install 180 MiB, remove 0 B).

It seems that we should either revisit the stdout/stderr filter installed in Mock, or the one we have in copr-rpmbuild. Not sure, or maybe there are some options in DNF5 to make the output more "logger" friendly? @evan-goode

I think rpm-software-management/mock#1261 is the main problem here, but even after changing Mock to invoke DNF 5 with a pipe on stdout and not a PTY, the logs are still garbled due to rpm-software-management/dnf5#1058.
