trackDb: the five dead iframeUrl settings, refs #37595

The PDB ones framed http://www.pdb.org/pdb/explore, which is plain http on an
https page and now redirects to a port that does not answer.  Point them at
https://www.rcsb.org/structure/, the URL wuhCor1 already uses.

The four NCBI ones cannot be framed at all - nuccore sends
X-Frame-Options: SAMEORIGIN - so they become a url instead, which gives the
Outside Link that these tracks never had.

While testing, the GenBank Chains details page on hg19 turned out to abort with
"Input to %-s should be created with safe functions" before printing anything:
its idInUrlSql used %-s.  Quoted %s instead, and the page renders again.
