Replace 'sc_prohibit_semicolon_at_eol_in_python' with generic 'sc_flake8' rule
to check python code style.

Now 'sc_flake8' just check the error E703: 'statement ends with a semicolon'.
In future, we could use '--select' to introduce more rules.


Nice, less language parsers using regexes in libvirt!

I don't think this line is necessary - we can just use the return value
from flake8


also, the libvirt-dbus invocation is using --show-source to be more
helpful
