time/rt: Fix up leap-second backport for RT changes
The leap-second backport broke RT, and a few changes had to be done.
1) The second_overflow now encompasses ntp_leap_second, and since
second_overflow is called with the xtime_lock held, we can not take that
lock either. (this update was done during the rebase).
2) Change ktime_get_update_offsets() to use read_seqcount_begin() instead
of read_seq_begin() (and retry).
