I agree that this makes this set of three tests harder to follow, as
we expect a root cert to *not* be set locally.  Keeping the behavior
documented in each individual string would be better, even if that
duplicates more the keys in those final strings.

Another thing that Horiguchi-san has pointed out upthread (?) is 003,
where it is also possible to trigger failures once the environment is
hijacked.  The attached allows the full test suite to pass without
issues on my side.
