lists: drop leading/trailing whitespace

This is a workaround for presumably alterator-pkg's misbehaviour given a pkglist with a line ending with a space character; my particular case grew from @E2K suffix resulting in "%name@e2k %name@e2kv4" which, in its turn, became "%name " in e2k-arch build. Installer complained about being unable to install in selected configuration with /tmp/install2.log "clarifying" the problem to be %name being unavailable (while %name package was there in both RPMS.main and metadata)... not obvious at all! So while downstream should be hardened either, let's do what we can do here.
