test/support.py: remove TESTFN if it is a directory
Because of my previous commit (r81171), test_os failed without removing TESTFN
directory (shutil.rmtree() was broken). Some buildbots still have a @test
directory and some tests fail because of that.
The bug is reproductible with:
mkdir @test
touch @test/abc
./python Lib/test/regrtest.py test_site
