install python-xml on SUSE/openSUSE only if python2 is installed

raw_install_python.yml: on SUSE/openSUSE, install python-xml package only
if python2 is installed already

Background:
On SLES 15.x / openSUSE Leap 15.x, the python2 package `python-base` provides
/usr/bin/python, while python3 only provides /usr/bin/python3.
