  tests: add GITTEST_SLOW env var check
  
  Writing very large files may be slow, particularly on inefficient
  filesystems and when running instrumented code to detect invalid memory
  accesses (eg within valgrind or similar tools).
  
  Introduce `GITTEST_SLOW` so that tests that are slow can be skipped by
  the CI system.
