package/asterisk: use package's DL_DIR
Since we reworked the download infra, the location for packages to look
for their files has moved to a per-package directory.
For systems where a download of the asterisk sound files was already
done in a version prior to the rework, all was working fine so far,
because the files were indeed in the main DL directory.
But for systems where the download is first attempted after the rework,
the files are not found (even though they are properly downloaded).
Fix the location where asterisk looks for its extra files.
