test/stages: re-use downloaded files between runs

Browse source 
Create a cache directory with the scope of the stage test suit and
after each test is run cache the downloaded files for the `files`
source via the new `OSBuild.copy_source_data` method. Initialize
OSBuild with that cache directory, so previously downloaded files
get used between different stage tests.
