This change updates httpclient tests to use `${test.main.class}` in `@run` tags
instead of explicitly referencing the test class name.
This aligns with the newer jtreg and avoids issues when
tests are copied and the class name is not properly updated.
Only `@run` tags are modified. Other tags (e.g. `@build`) that may still
contain explicit class references are intentionally left unchanged for now,
but can be updated(removed) if desired.
The number of changes is relatively large due to the mechanical nature
of the refactoring. Thanks for taking a look.
