Subject: linux/update.sh: update linux-libre too

update-libre.sh doesn't commit by default so that it can be used as an
updateScript, where I don't think auto-committing is the norm.

The generated commit messages say "linux-libre_latest" rather than
"linux-libre", because even though linux-libre will also be rebuilt,
it's linux-libre_latest that is more likely to need it.
