rtc: test: Also test time and wday outcome of rtc_time64_to_tm() 



To cover calculation of the time and wday in the rtc kunit test also check
tm_hour, tm_min, tm_sec and tm_wday of the rtc_time calculated by
rtc_time64_to_tm().

There are no surprises, the two tests making use of
rtc_time64_to_tm_test_date_range() continue to succeed.
