Introduced by pull request https://github.com/dCache/dcache/pull/906.

The refactoring into new directories was not applied to the branch
when the patch was applied, and the build process did not catch
the incorrect package names which resulted.

Also neglected to eliminate two jndi properties, the presence of
which prevent httpd from booting.
