Time.parse based from non-Time object

* lib/time.rb (Time.make_time): as the document states, the second
  argument of `Time.parse` may be a non-`Time` object which does not
  have `getlocal` method, assume it is in the local time in the case.
  based on the patch by nkmrya (Yasuhiro Nakamura) at
  [ruby-core:68775].  [ruby-core:68775] [Bug #11037]
