Minitest upgrade broke build

load_missing_constant is a private method that basically plays the role of const_missing.
This method has an error condition that is surprising: it raises if the class or module
already has the missing constant. How is it possible that if the class of module has
the constant Ruby has called const_missing in the first place?

The answer is that the from_mod argument is self except for anonymous modules, because
const_missing passes down Object in such case (see the comment in the source code of the
patch for the rationale).

But then, it is better to pass down Object *if Object is also missing the constant* and
otherwise err with an informative message right away.

Use `Base.strict_decode64` instead of `Base.decode64`

Fix issue with Kernel#silence_stream leaking file descriptors

Calling Kernel#silence_stream creates a new file descriptor which isn't
closed after it is used. As a result calling silence_stream multiple
times leads to a build up of loose file descriptors and can cause issues
in environments where garbage collection isn't run often.
