To avoid proliferation of versions, I suggest the following policy: the
oldest LTS release still receiving maintenance updates + the most recent
release for distributions that offer LTS releases.
For CentOS, this means CentOS7 and CentOS Stream 9 (since CentOS are all
"long-term support", this is just the oldest and the newest among
currently supported).
For Ubuntu, this means Ubuntu 18.04 (previous LTS are in "security fixes
only" mode) and Ubuntu 21.10. Recent Ubuntu attempts to be interactive
during the configuration of tzdata, required some additional setup.
In the common installation script, the logic for handling a
configured/built local directory breaks if `gmake` is detected as the
make binary; `make distclean` then fails inside the container because
not all systems have `gmake` symlink. Remove that attempt of a
workaround completely, just require that the host directory is clean.

Recent Linux kernels (5.3 and newer) use rsync to copy headers around.
Add the rsync package to the list of dependencies.

Make the creation of docker images easier so that CTNG_UID/CTNG_GID have
a default value if it's not explicitly specified when building. This
will allow publishing of images on various package repositories (e.g.
docker hub, gitlab containers). dmgr.sh can still be used to set the
UID/GID to that of the current user when building a custom container.
