Remove dangling reference to $with_edirectory

Remove a reference to eDirectory that persisted after support for
eDirectory was removed.  Almost certainly harmless anyway.
Remove some apparently-accidental debug whitespace
Fix checking unencrypted PKCS12: twice

The test, as submitted, included a copy/paste error which caused it to
test PKINIT using unencrypted PKCS12 bundles twice, and to not test a
DIR: location containing unencrypted PEM-formatted keys at all.
Fix a typo that caused us to not skip removing "."

When attempting to clean the files out from our temporary directory,
correct the test which was supposed to let us skip over "." and ".." so
that we actually don't try to remove them with remove().
Make reassembled PKCS11 names parseable

The reassembled names used "," as a separator between attributes, when
passed-in values use ":".  This was due to the original submitter being
confused - they weren't intended to be different.
