On case-insensitive filesystems it is not such a good idea to have
directories that only differ in case. Packages should be always split
into lowercased directories.
The test data is modified to include some packages starting with
uppercase letters. The example in code can be verified by running
`nosetests --with-doctest`.

Previous test data was insufficient for proper testing.
Test compose runs and depsolving tests require precisely
set NVRs, dependencies, sub-packages, etc.
Using rpmfluff for these would be an overkill, it's better
to create RPMs directly from specs.
