java-re/libreoffice: disable shared for the moment

This reverts commits d23929f7
(partially) and 3c52286b.

This issue is in slapos.core, slapos/testing/check_software.py:

      '*/parts/libreoffice-bin/*',
      '*/parts/java-re*/*',

We'll reapply the changes after (or at the same time as)
slapos.core is updated.
