[PATCH v5 0/4] Fix cross-build from base-apt when custom DISTRO name used

[Uladzimir Bely <ubely@ilbers.de>]

This patchset is mostly intended for downstreams that prefer
renaming DISTRO variable (like `meta-iot2050`) and use
ISAR_CROSS_COMPILE = "1".

This also fixes the case with cross-build on raspberry targets
from cached base-apt repo. While it uses separate repositories
for host (Debian) and target (Raspbian) distros, base-apt is
splittend onto two parts corresponding to the original repos.

Also, testsuite repro tests were updated to cover crosss-build case
and raspberry target is now used in them.

Additionally, download directories for deb packages are now rely
on {HOST_}BASE_DISTRO variables instead of {HOST_}DISTRO.

Changes since v4:
- Normalized download directories (patch 4)

Changes since v3:
- Renamed BASE_HOST_DISTRO to HOST_BASE_DISTRO.

Changes since v2:
- Cleaned garbage in commit message for patch 2.

Changes since v1:
- Support cached cross-build from base-apt for different base distros
for host and target (e.g. raspberry).

Uladzimir Bely (4):
  Populate base-apt from both DISTRO and HOST_DISTRO download dirs
  testsuite: Run signed repro test in cross mode
  testsuite: Replace bananapi with rpi-arm-v7 in signed repro tests
  Normalize deb download dirs when custom DISTRO used
