tests/str: Rework sysinstall-tests to be an entrypoint

Prep for creating more types of tests.

Move copying of `tests/` into the sysinstall-tests rather than `overlay-git`
as not all test types may need that.

Factored out of https://github.com/ostreedev/ostree/pull/1501

Closes: #1509
Approved by: jlebon
