Since we're sharing functions between test scripts, move greenprint(),
the most rewritten function in the history of the project, to
shared_lib.sh and source it everywhere.
- Handle the array responses from the new weldr-client (>= 35.6).
- Move the `get_build_info` function to shared_libs.sh to source and
reuse in multiple places.
can be used for conditionally enabling parts of the test scripts:
source /usr/libexec/tests/osbuild-composer/shared_lib.sh
if nvrGreaterOrEqual "osbuild-composer" "41"; then
.... do some more testing ...
