Sort repackaged libraries in a reproducible Maven build

Browse Source 
When a Maven build is configured to ensure reproducibility, any
libraries added to `BOOT-INF/lib` in a jar archive or to `WEB-INF/lib`
in a war archive by the Spring Boot plugin repackaging should be
sorted by name to ensure a stable and predictable order.
