tests: tinycrypt: build only on native_posix

Move tinycrypt related header into test and make those tests only build
on native_posix. The tests are unit tests, ie. testing tinycrypt
functionality only without any dependency on the underlying system.

Long term we should move those to be true unit tests and create
functional and integration tests that use tinycrypt in the context of
Zephyr and for real use-cases.
