Bound three string and XML reads that analysis flagged

- On macOS, the path from _NSGetExecutablePath is cut at its first NUL
  found inside the buffer, in place of strlen, which reads until a NUL
  wherever it is.
- The table test measures its C strings with std::string_view.
- The Bazel reporter test reads the JUnit report and rejects a document
  type before parsing it, so no entity, external or internal, is ever
  expanded.
