git fetcher: Add exportIgnore parameter

Browse source 
Enabled for fetchGit, which historically had this behavior,
among other behaviors we do not want in fetchGit.

fetchTree disables this parameter by default. It can choose the
simpler behavior, as it is still experimental.

I am not confident that the filtering implementation is future
proof. It should reuse a source filtering wrapper, which I believe
Eelco has already written, but not merged yet.
