D1699: tests: avoid echo with backslash escapes

REVISION SUMMARY
  Some shells' echo (e.g. Bash's) do not interpret backslash escapes by
  default, while others shells' do (e.g. Dash's). This led to a failure
  in test-run-tests.t. We could switch to the more compatible printf,
  but using a heredoc seems simpler, so that's what this patch does.
  
  For anyone who wants to test this for themselves, remove the "unset
  HGTEST_SHELL" line in helper-runtests.sh and pass
  e.g. "--shell=/bin/dash" to the test runner.
