ci(release): fix RPM python binding and DEB libxml2 dep on new distros

Two release-blocking failures surfaced when the package matrix gained
AlmaLinux 10 and Ubuntu 26.04:

- AlmaLinux 10 (Python 3.12) no longer bundles setuptools with
  python3-devel, so the python binding failed with 'The setup requires
  setuptools'. Add python3-setuptools to the RPM build-dep list; it is
  harmless on EL8/EL9 and needed on Fedora too.

- Ubuntu 26.04 bumped libxml2 to 2.14 and renamed the runtime package
  from 'libxml2' to 'libxml2-16'. Make the fpm dependency an
  alternative ('libxml2-16 | libxml2') so apt resolves it on every
  distro in the matrix.
