Don't transform imports that are already relative. 2to3 turned
from . import refactor
into
from .. import refactor
which broke the transformation of 2to3 itself.

Make 2to3 run under Python 2.5 so that the benchmark suite at
http://hg.python.org/benchmarks/ can use it and still run on implementations
that haven't gotten to 2.6 yet. Fixes issue 8566.
