It has not been a dependency since at least 4.13. Remove its mandatory check
from ./configure.
Annotate the dependency in the CI dockerfiles, and drop them from CirrusCI and
TravisCI.

We can't drop the 32bit libc from the existing containers, because they are
used on older Xen branches as well.
However, we can avoid the dependency being propagated into newer conainers
derived from our dockerfiles.
No functional change.
