remove dead code from sage-ptest

[wjp]

The sage-ptest parallel doctesting script has some dead code in it: a function run that's unused, and a -sage flag that triggers a call to a no longer existing sage-doctest_tex script.

I'm attaching a patch that cleans this up, and as a side effect allows sage-ptest to test files with a .sage extension.

Written as advertised, run() routine is never called, doctest_tex is no longer shipped as part of Sage.

Applies cleanly and works fine in limited testing.

Positive review.
