[PATCH v3 0/1] deb-dl-dir: Use dpkg-deb --field in debsrc_download

[Uladzimir Bely <ubely@ilbers.de>]

Debian `control` file inside .deb package may not contain `Source` field.
So, this field is virtual and the simplest way to request it - using
${source:Package} and ${source:Version} on "dpkg-deb --show --showformat".

While in bullseye this is currently broken, the patch simply emulates
the same logic using dpkg-deb --field. Initially, we try to get source
package name and version using from `Source` field and if it fails, we
just use `Package` and `Version` values.

Changes since v2:
- Replaced if/then/fi by one-line alternative
- Added comments in the code about reverting the patch when bug #1004372
in Debian is fixed

Changes since v1:
- Fixed commit message (should be BASE_REPO_FEATURES ?= "cache-deb-src",
but not ISAR_USE_CACHED_BASE_REPO)
