RFR: 8360882: Tests throw SkippedException when they should fail [v3]

[Matthew Donovan]

> This PR updates `ArtifactResolver.fetchOne()` to throw an IOException instead of SkippedException. This allows tests to determine of a missing "artifact" should be treated as a failed or skipped test.`OpensslArtifactFetcher` is also updated to only throw SkippedException if OpenSSL is not available on the test platform.

Matthew Donovan has updated the pull request incrementally with one additional commit since the last revision:

  updated PKCS11Test to catch IOException and throw Skipped
