etc: teams: Parse 'From' commit more leniently.

Browse source 
When a Change-Id is used, patman prepends a Message-Id field on the first line
of the patch, which broke the assumption that the 'From $commit' line must
appear on the first line.

* etc/teams.scm.in (git-patch->commit-id): Loop each line of the file until a
match is found.  Update doc.
