[llvm] [Debuginfod] Remove `llvm-debuginfod-find` lit tests that used python http server.

[noajshu]

Summary

These tests depend on ThreadingHTTPServer which was not introduced until python 3.7 so we might as well delete them to avoid issues.

[Hahnfeld]

I don't know if simply removing the tests is the right course of action, but yes I'd really love to get a clean check-all with Python 3.6

Sorry for the long delay; it looks like most of this functionality is now covered by the llvm-debuginfod.test for the debuginfod server. LGTM.
