runtests: fix output for skipped pythons

I have Pythons 2.7 and 3.4 installed.

Before the patch I had the following output:

    $ ./runtests pym/portage/tests/resolver/test_blocker.py
    Testing with Python 2.7...
    Testing with Python 3.4...

    Summary:
    | Version    | Status
    |--------------------
    | 2.7        | PASS
    | 3.3        | PASS

After the patch:

    $ ./runtests pym/portage/tests/resolver/test_blocker.py

    Testing with Python 2.7...
    Skip Python 3.3...
    Testing with Python 3.4...
    Skip Python pypy...
    Skip Python 3.5...

    Summary:
    | Version    | Status
    |--------------------
    | 2.7        | PASS
    | 3.4        | PASS
