configure: Flip default of target_nptl

Most targets either (a) support threading or (b) don't have a
linux-user/bsd-user target, so make it default to 'yes', with those
targets that don't support threading having to specifically say so.

This is a mechanical no-behaviour-change commit; some of the
"no" entries it adds will be taken out in later patches.
