Rationalize directory handling around ca-certificates.crt

Now, ca-certificates.crt is always in the main certs dir, because we
have been careful about builtin vs pkgsrc paths.  So the directory
must exist (because it was checked earlier).  Instead, check for the
ca-certificates.crt file existing.  Add more questioning comments.

Based on a patch by J. Lewis Muir.
