python3: update killdaemons and run-tests print and exception syntax

test-run-tests.t still passes fine on Python 2.6. run-tests.py --local
no longer fails with syntax errors, and now fails looking for xrange.

Most changes done with

2to3 -w -f numliterals -f except -f print tests/run-tests.py tests/killdaemons.py

after which one import was fixed in run-tests and a __future__ import
was added.
