[RFC PATCH] classes/deb-dl-dir.bbclass: Download src with retry mechanism

[Srinuvasan A <Srinuvasan_A@mentor.com>]

From: Srinuvasan A <srinuvasan_a@mentor.com>

Sometime the source packages are not downloaded successfully due to
the low speed network, hence the builds get fails with timeout issue

Added a mechanism to attempt multiple try till the download get success.
