Always test against a copy of the testdata. This should avoid problems with the testdata being trimmed out by `cargo publish`.
On macOS the tempdir goes through a symlink so paths may not appear the same: canonicalize before comparing.
Get copy symlinks on WIndows, since that's now used in copying some testdata
Mostly guards against mutating it to . but seems like something that we expect should always be true, anyhow.
Unlikely to ever be a practical problem here

Always test against a copy of the testdata.
This should avoid problems with the testdata being trimmed out by
cargo publish.The motivation is that Debian, or others who package from the tarball, can run the tests after building.
Most of the changes in this are connected to
cargo publishbehavior of excluding various files including symlinks,Cargo.toml, and.cargo. This PR renames them and recreates them during the test, in the process of copying the testdata to a temporary directory. Aside from anything else this should make sure that each test is hermetic.Also, since we're now creating the symlink from a test, we can also do that on Windows and check that it works.
This also adds a CI job that checks that the tests do pass in an unpacked tarball.
Also, delete a lot of Insta snapshots that had accumulated and are no longer needed.
