Subject: [PATCH] zypper: support transactional-updates (#3164) (#3193)

* zypper: support transactional-updates

- Check if transactional updates are in use by checking for the
  existence of /var/lib/misc/transactional-update.state
- Prefix zypper-commands with /sbin/transactional-update --continue --drop-if-no-change --quiet run
  if this is the case

fixes ansible-collections/community.general#3159

* re-add get_bin_path for executables

* fix typo

(cherry picked from commit 6033ce695bc891828887019439ecf11668f58086)
