remove explict references to SAGE_ROOT in the doctesting framework

[ohanar]

The new doctesting framework expects the sage library's source code to be in SAGE_ROOT/devel/sage which will no longer be the case once we switch layouts. Using the SAGE_SRC environment variable will make the transition much easier.

Apply attachment: trac14331.patch then attachment: trac14331_missed.patcho the sage library.

Definitely want this in. We didn't spend so much time on #13432 to be undone by the patch bomb from the new doctesting frame work. We want it ASAP. Thanks for spotting it Andrew and thanks for the review David.

Hopefully it doesn't interfere with any of the follow up of #12415.

I missed one disguised reference in my first patch, so I've attached a fix for that.
