Warn at configure time when time_t is unsigned

Inspired by #8042.

As far as I know, OpenVMS is the only place you're likely to hit an
unsigned time_t these days, and Tor's VMS support
is... lacking. Still worth letting people know about it, though.

- Warn if building on a platform with an unsigned time_t: there
are too many places where Tor currently assumes that time_t can
hold negative values. We'd like to fix them all, but probably
some will remain.
