Parametrize tests for `pathlib.Path.copy()`

[barneygale]

We should be able to parametrize tests for pathlib's ReadablePath.copy(), e.g.:

• Copy from Path to Path
• Copy from Path to WritableZipPath
• Copy from ReadableZipPath to Path
• Copy from ReadableZipPath to WritableZipPath

Unfortunately this breaks some deep assumptions in the existing test classes, so I think we should create new suites somewhere in test.test_pathlib.

I've already made a start on this, but I'll stop making changes and put a PR up so that others can contribute.
