Update debian package versions to use git commits

The Debian packaging has been changed to reflect all the
git commits under the directory, and not just the commits
to the metadata folder.

This ensures that any new code submissions under those
directories will increment the versions.

- The commit "Add debian package for virt/cloud-init"
  (SHA 6d1244bda9) was choosen to be the SRC_BASE_SRCREV
  of the cloud-init's metadata because is the commit that
  creates the debian directory with build files structure.

- The commit "Add debian package for virt/kvm-timer-advance"
  (SHA 4cb5d17a7f) was choosen to be the SRC_BASE_SRCREV
  of the kvm-timer-advance's metadata because is commit
  creates the debian directory with build files structure.

- The commit "Add debian package for virt/libvirt-python"
  (SHA 6420a976d3) was choosen to be the SRC_BASE_SRCREV
  of the libvirt-python's metadata because is the commit that
  creates the debian directory with build files structure.

- The commit "Debian: Add build structure for virt/libvirt"
  (SHA 1f37f8b5d4) was choosen to be the SRC_BASE_SRCREV
  of the libvirt's metadata  because is the commit that
  creates the debian directory with build files structure.

- The commit "Debian: Add build structure for virt/qemu"
  (SHA 75a234904f) was choosen to be the SRC_BASE_SRCREV
  of the qemu's metadata because is the commit that
  creates the debian directory with build files structure.

Test Plan:
PASS: build-image
PASS: build-pkgs -c -p cloud-init
PASS: build-pkgs -c -p kvm-timer-advance
PASS: build-pkgs -c -p libvirt-python
PASS: build-pkgs -c -p libvirt
PASS: build-pkgs -c -p qemu
PASS: commit a file change under cloud-init, rebuild and
      see that the cloud-init version has increased.
