release zypp lock after software finish action (bsc#1258188) (#3271)

## Problem

It is not possible to have zypper call in post install scripts as agama
still holding zypp lock.

- https://bugzilla.suse.com/show_bug.cgi?id=1258188


## Solution

release zypp lock together with finish action which should be the last
one software stack do.


## Testing

- *Tested manually* with post install script and zypper works.
