package/openjdk: copy all directories and files when installing

Several directories and files are currently not installed during the
target installation, these include:
  - conf
    Several configuration files, including security configuration files which
    may be necessary for running various java applications.

  - legal
    This directory contains legal notices that some java applications may
    require, as they may print legal information and will throw exceptions at
    runtime if the legal files are not present on the system.

  - release
    This file contains a list of modules included in the image.

Because these directories take up less than of megabyte extra, it is not an
issue to install all of them.
