cleanup: remove run-postinsts, dpkg status-old

- initramfs: remove run-postinsts package, it has no purpose as there is
  no package manager inside the initramfs;
- rootfs: remove run-postinsts if the package manager is DPKG/APT, since
  it duplicates the existing dpkg-configure.service installed by the
  dpkg recipe;
- rootfs: cleanup DPKG backup file 'status-old', it contains information
  about packages before the final installation stages of the rootfs
  build process (completely irrelevant for the end user), saves >500kB;
