Replace awk with ansible regex_search on build-test-packages

Some jobs[1] are not working with current awk command to get
a substring from rdopkg output. This patch replaces with ansible
regex_search instead.
This patch also fix the 'host' value extract from zuul vars. The
previous value is invalid as host when cloning code with git module.
This git checkout isn't failing since the previous step, that copies
cloned code from zuul working dir is always executed with success.
