Bug#907863: libeclipse-osgi-java, libequinox-osgi-java: error when trying to install together

[Emmanuel Bourg]

Control: reassign -1 libeclipse-osgi-java
Control: affects -1 libequinox-osgi-java

libeclipse-osgi-java will replace libequinox-osgi-java. I forgot to add
the proper Breaks/Replaces fields.
