Revision field in the json data generated by run-webkit-tests is empty since migration to git
https://bugs.webkit.org/show_bug.cgi?id=244960

Reviewed by Jonathan Bedard.

The script run-webkit-tests generates a json file with the information of
the test run (usually named full_results.json).

This json included a "revision" field with the SVN revision of the checkout.
But since the migration to git this "revision" field is null.

Fix it by setting as revision number the canonical identifier "number@main"
if available, otherwise default to the git commit hash.
