[fuchsia_roller] Use 14-char git hashes in footer

The roll_comment recipe uses this footer to do a `git log` via gitiles
to get a list of the rolled commits to comment on. However, when using
7-character hashes gitiles sometimes detects a hash ambiguity and
returns a 404 (this doesn't make sense, because 7 characters leaves room
for >268 million commits and fuchsia.git only has 75,000). So we use a
longer hash to make it much less likely that the hash will be ambiguous,
while still keeping the footer line under the git commit message line
length limit of 72 characters.

See http://b/148289050 for discussion.
