os-release, lsb-release: Fix os-release diversion and drop obsolete l…

…sb-release files

 * os-release: Divert /usr/lib/os-release instead of /etc/os-release in order
    to accommodate particularities in the lsb-release code of Debian.
    Normally, /etc/os-release should override /usr/lib/os-release, but the
    mentioned Debian code does not respect that unless extra environment
    variables are set.
  * /etc/lsb-release is not needed anymore on Buster and not used by lsb-release; drop it.
  * Document a harmless warning occurring at install time from dpkg-divert.
 * Bump package version.
