Set BREE to at least JavaSE-1.6 when building OSGi bundles.

Since Fedora 17, we need an Execution Environment of at least JavaSE-1.6
for Eclipse bundles. Eclipse Juno platform bundles depend on
javax.annotation. In Fedora this is provided by geronimo-annotation, but
has a dependency on javax.lang.model (since 1.6).
