Duplicate the result of archive_entry_pathname.
After the libarchive upgrade from 2.4.12 to 2.4.14, our usage of
archive_entry_pathname became dangerous. We were using the result of that
function even after calls to archive_entry_set_pathname.
With 2.4.14, the entryname becomes wrong after these calls, and so all the
future use of entryname are bogus. entryname is used quite a lot for
logging, so that's not so bad. But it's also used for the backup handling,
so that's not very cool. For example, reinstalling a package with backup
entries will erase all the md5 entries from the DB, because they won't be
found back.
entryname is now a static string so that we can easily keep the result of
archive_entry_pathname.
