[rust] improvements in agama logs store

[mchf]

Problem

• some information were missed in the result

Solution

• added journal output for (new) agama-web-server
• collected package versions (either .packages.root or "rpm -qa")
• minor improvements - do not include empty files (when command produces no output) into the resulting archive; do not mask errors reported by the backend (either authentication required)
• added service running busctl monitor on agama's bus in the background and collectin errors in dbus.log, the log file is then put into the resulting archive

Testing

• Tested manually

It looking much better now. Thanks!

One match and three nested "ifs" look too much to me :-) What about something like:

copy_items(&[self.src_path.as_str()], dst_path, &options)
    .map_err(|_e| io::Error::new(io::ErrorKind::Other, "Copying of a file failed"))?;

if let Some(file_name) = dst_file.file_name().and_then(|fname| fname.to_str()) {
    if file_name.starts_with(".") {
        let name = file_name.trim_start_matches(".");
        let _ = fs::rename(dst_file.clone(), dst_file.with_file_name(name));
    }
}

Ok(())

you're suppressing my creativity ;-)

I'll look into it ...
