chgserver: add fastannotate config section to sensitive list
Depending on the config value of `fastannotate.modes`, the fastannotate
extension can do different things in uisetup. Depending on value of
`fastannotate.server`, it can register new wireprotocol capabilities.
This fixes test-fastannotate-hg.t, test-fastannotate-protocol.t and
test-fastannotate.t with chg.
