Summary: A few changes related to logging: - prepend `Scudo` to the error messages so that users can identify that we reported an error; - replace a couple of `Report` calls in the RSS check code with `dieWithMessage`/`Print`, mark a condition as `UNLIKELY` in the process; - change some messages so that they all look more or less the same. This includes the `CHECK` message; - adapt a couple of tests with the new strings. A couple of side notes: this results in a few 1-line-blocks, for which I left brackets. There doesn't seem to be any style guide for that, I can remove them if need be. I didn't use `SanitizerToolName` in the strings, but directly `Scudo` because we are the only users, I could change that too.
