Subject: Add ability to download package from web interface

After adding filename to the database, this is a rather simple request (see
FS#19546). Right now the "randomly" chosen mirror happens to always be
mirrors.kernel.org as it is the only one filed under the 'Any' country which
is what we screen on. Perhaps this logic could be improved in the future but
I don't see these links being all that high traffic anyway.
