Fix installation when CA subject DN has escapes

There were several bugs across several projects preventing
installation when the CA subject DN contains characters that need
escaping in the string representation, e.g.

  CN=Certificate Authority,O=Acme\, Inc.,ST=Massachusetts,C=US

The package versions containing relevant fixes are:

- 389-ds-base 1.4.0.20 (we already require >= 1.4.0.21)
- pki-core 10.5.5 (we already require >= 10.6.8)
- certmonger 0.79.7 (this commit bumps the dependency)

With this change, installation will now work.  Integration tests are
left for a subsequent commit.
