add helper to respawn modules with system python

The seboolean, selinux, firewalld, and firewalld_info modules depend on
system bindings that are only available for the default system python
interpreter. ansible-core is not packaged for the default system python
interpreter on RHEL 8 and 9. When automatic interpreter discovery does
not occur (e.g. when using implicit localhost [1]), ansible-core will
not use the system interpreter to run ansible modules and the
aforementioned modules will not work even if the bindings are installed.
The RHEL ansible-core maintainers as well as the EPEL ansible and
ansible-collection-* package maintainers (inc. me) have gotten multiple
bug reports about this. We have been telling people to fix their setup
to use the correct Python interpreter. Fortunately, ansible-core 2.11
and above have a module utility that'll respawn modules to use the
correct system interpreter.
