Bug #15506: ArgumentError on some ordinal dates

[v49564 (Victor Bruley)]

Seems the bug was introduced with r64028:
Adding the difference between two ordinal dates (source:lib/time.rb#L210 : day += diff) results in month days superior to 31 for dates at the beginning of a month, causing the out of range error.

require "time"
Time.strptime("91095", "%y%j")
 => 1991-04-05 00:00:00 -0400

Time.strptime("91093", "%y%j")
Traceback (most recent call last):
