Add basic `sink.text.details` tests

This patch adds very basic `sink.text.details` tests to at least keep
track of the generated text's format. The tests test each initialization
parameter individually, and some combined with `compact=yes`.

As of this patch, all tests pass `with-stream-name=no` to initialize the
`sink.text.details` component because the `src.ctf.fs` component uses
absolute paths to set stream names and this is not compatible with
static expectation files.

Future tests should use a custom source to check how `sink.text.details`
writes the stream name property.
