dgit: Implement clean_tree_check for mode -wc

This part of the fix for #910705.  This makes -wc actually work with
build_source.

But per the discussion in #910705 we want to implement some checking
in dpkg-source[-d] mode too.

We need to teach the test suite about this notion of checking
cleanlines rather than cleaning.  For now we wildcard C*.
