feat(package): add commit info to raw list output

[line-o]

xst package list --raw output has a new entry for each package. commit is either null or, when repo:meta/@commit-id is found an object with

• id: the value of @commit-id, the hash from which this XAR was built
• time: the value of @commit-time

The test-app was modified to include both attributes in its repo.xml
