puppet: force bouncycastle-api and junit plugins

From the LTS changelog of 2.176.2 (2019-07-17):

     Make sure detached plugins (plugins whose functionality used to be
     part of Jenkins itself) are installed upon Jenkins startup when
     needed as implied dependencies of other plugins which were already
     present. This simplifies compatibility for specialized installation
     scenarios not using the update center, such as when Jenkins is run
     from a Docker image prepackaged with some plugins. (issue 57528)
