oracle-java-installer packages mess around with distribution packages

[Matthias Klose]

The oracle-java-installer packages mess around with distribution packages, nam
ely the postinst runs

  #create default-java symbolic link
  rm -rf /usr/lib/jvm/default-java
  ln -s /usr/lib/jvm/java-7-oracle /usr/lib/jvm/default-java

the prerm runs

  rm -rf /usr/lib/jvm/default-java


This is not acceptable. Please don't mess around with the standard installation
in such a way.  For now i'll add unconditional conflicts to these installer
packages in default-jre-headless so that people know what they get when using
these packages.

Thanks, Matthias
