dockerfiles: Update the systemd libs used to build docker image (flue…

…nt#3177)

The libraries created in the docker image can not read the journal db in newer
versions of systemd. This specifically impacts users that run systemd `246` or
above on their host server:

> * systemd-journald gained support for zstd compression of large fields in
> journal files. The hash tables in journal files have been hardened against
> hash collisions. This is an incompatible change and means that journal files
> created with new systemd versions are not readable with old versions. If the
> $SYSTEMD_JOURNAL_KEYED_HASH boolean environment variable for
> systemd-journald.service is set to 0 this new hardening functionality may be
> turned off, so that generated journal files remain compatible with older
> journalctl implementations.

(Taken from https://github.com/systemd/systemd/blob/v246/NEWS)

This commit uses the backported version of the systemd libs, which are `247` for
Debian buster. Fixing it for most distributions.

It might be worth considering having a separate build stage for systemd, that
would give better flexibility of the version shipped in the image.
