[PATCH 1/2] deb-dl-dir: Avoid multiple find run on export

[Anton Mikanovich <amikan@ilbers.de>]

We are running find on isar-apt repo for every new deb in cache.
This can be optimised by collecting isar-apt content once and compare
deb name with this list later.
It can be also usefull for the future isar-apt lock protection.
