[JPS] Ignore classpath from facets to exclude jars from gradle build

Reimport after `./gradlew build` adds jars from gradle's `build/libs` to facet's classpath. That causes problems with JPS build, because it doesn't see changes in out folder, but see unchanged jar, so changes don't apply.

#KT-51873 Fixed
