Eliminate INDEX.LIST from Spring jar META-INF dirs

The contents of this file could be problematic as they were generated
by spring-build with "org.springframework.core.jar" EBR-style naming,
but this naming is incorrect when dealing with Maven-central style
artifacts, e.g. spring-core.jar.

While a well-formed INDEX.LIST may speed up classloading, the simplest
solution to the issues listed below is simply to eliminate the file.
This also means consistent treatment across 3.1.x and 3.2.x artifacts,
as the new Gradle build in 3.2.x does not create these index files.

Issue: SPR-6383, SPR-9208
