Move packages into compliant distro/codename hierarchy

This is a few tests of using the new distro/codename packaging hierarchy.

Changes include:
- Move base/base-passwd/debian to base/base-passwd/debian/bullseye as
  this patched package is specific to bullseye. Also add
  'revision.stx_patch: 9' to meta_data.yaml so that the .stx package
  version remains consistent.
- Move base/systemd-presets/debian to base/systemd-presets/debian/all as
  this packages should be the same for all flavors of debian.
- Move security/efitools/debian to security/efitools/debian/bullseye as
  this patched package is specific to bullseye. This also tests a
  package with src_files in the meta_data.yaml and requires an update
  once the package is relocated.

Test Plan:
 - PASS: stx-init-env --rebuild, downloader, build-pkgs -a, build-image
