basic/calendarspec: fix assert crash when year is too large in calendarspec_from_time_t()

gmtime_r() will return NULL in that case, and we would crash. I committed the reproducer case in fuzz-regressions/, even though we don't have ubsan hooked up yet. Let's add it anyway in case it is useful in the future. We actually crash anyway when compiled with asserts, so this can be easily reproduced without ubsan. oss-fuzz #6886.
