Nightly Windows build failures on both 32-bit and 64-bit

Our current Windows nightly builds fails for two different reasons right now:

src/feature/stats/rephist.c:2012:34: error: format ‘%ld’ expects argument of type ‘long int’, but argument 5 has type ‘time_t {aka long long int}’ [-Werror=format=]
   tor_asprintf(&hs_stats_string, "%s %s (%ld s)\n"

and

src/test/test_stats.c: In function ‘test_rephist_v3_onions’:
src/test/test_stats.c:527:22: error: overflow in implicit constant conversion [-Werror=overflow]
   update_approx_time(10101010101);

Patch coming up.
