Revert "Exclude bouncycastle key files to fix SecurityException upon plugin-api"

During server startup the warning:

  Disabling cipher <name>: JCE cannot authenticate the provider BC

is emitted for each cipher [1],

and when using SSH, all git operations fail with the error:

  no matching cipher found [2].

This reverts commit 3420d83f39.
