libs/rpms : update for CentOS 7 removal

With the removal of CentOS 7, we can re-evaluate the rpm
installations.

We should not need virtualenv after https://review.opendev.org/712609

There should be no need for python-devel as we're python3

pyOpenSSL was added to workaround memory issues in
9e98f9435e (2015) ... I think we've
moved on.

pyxattr is not a package; remove it.

I don't see we need packaged m2crypto, which isn't a package on CentOS
8.  nor libxml2-python; these days it has wheels which should work
with the normal installation process.

centos8 has:

 * targetcli
 * pcp-system-tools (and no dstat)
 * iptables-services
 * java-1.8.0-openjdk-headless
 * kernel-modules
 * rsync-daemon

just as all supported fedora's do, so we can remove any matching here.
