Fix cabal projects using source-repository-package

Apparently we can get source-repo-packages in plan.json even when filtering
for `"style": "local"`(`UnitTypeLocal`). It's possible the root cause here
is a cabal bug as source-repository-package should really be treated more
like a tarball than a local package. Regardless we simply filter units by
actually checking for `uPkgSrc=Just LocalUnpackedPackage` instead of
relying on "style".

This fixes #99
