Subject: [PATCH] tests: Add basic smoke tests for Key

python-tuf has an extensive test suite for Metadata in general:
* I don't think python-tuf should stop testing Key just because it's now in
  securesystemslib
* Maybe it's not necessary to copy e.g. all serialization tests here?

Still, added a few basic tests for Key. Key is also used in the Signer tests.
