datetime: remove unused function datetime_gmtoff

The function `datetime_gmtoff()` has been introduced in commit
aec6fbac1f22 ("datetime: implement date.isdst") for a function
`datetime_increment_by()`. In commit 6ca072853034
("datetime: fix interval arithmetic for DST") the function
`datetime_increment_by()` has been updated and call of the
function `datetime_gmtoff()` was removed. `datetime_gmtoff` is
dead code now. The patch removes `datetime_gmtoff()`.
