[PATCH v8 15/16] sbuild: Fix debsrc_download for packages dependencies

[Uladzimir Bely <ubely@ilbers.de>]

With sbuild, build deps are internally installed in temporary sbuild
environment,so they don't appear in any external dpkg.log files.

With "cache-deb-src" base repo feature enabled, these such packages
are considered not to belong to current build, so their src packages
are not downloaded at image postprocess stage.

The patch fixes this by extracting dpkg.log files from the sbuild
environment to one common log file. This consolidated log is then
used at rootfs_postprocess to get source packages.
