git-p4: add P4 jobs to git commit message

When migrating from Perforce to git the information about P4 jobs
associated with P4 changelists is lost.

Having these jobs listed on messages of related git commits enables smooth
migration for projects that take advantage of e.g. JIRA integration
(which uses jobs on Perforce side and parses commit messages on git side).

The jobs are added to the message in the same format as is expected when
migrating in the reverse direction.
