ci: Make section emission really quiet

If you're emitting a section header under set -x, you will see:
+ section_start foo "foo"
+ x_off
[the section header]

This is kind of annoying. Instead of trying to squash it everywhere by
dancing around local set +x management, play some extremely stupid
tricks with shells to make sure we never emit it.
