I concur with the others here. Unless there are specific concerns about your ability to perform the job (and I would assume that you probably aren't applying for that kind of work anyway) you don't have to bring it up and, frankly, they can't even legally ask... at least in the U.S.
That said, getting job interviews these days is difficult for everyone. My advice is to use any business connections you have to try to get your resume in front of hiring managers (HR and "official channels" are usually big black holes for resumes), and keep trying, as frustrating as it seems.
