Subject: [PATCH] TT#45401 lib/get_debian_release: support Debian/buster +
 Debian/bullseye

Currently `/etc/debian_version` for Debian/buster systems includes:

buster/sid

So until we get the according version number via base-files, also
check for the codename instead. Make it more generic so it works for
any upcoming release that uses ".*/sid", to not run into the issue
again with e.g. the upcoming Debian/release codenamed bullseye (the
release expected after buster).

Thanks: Manuel Montecelo for improving my initial version
