Buck: Preserve SNAPSHOT suffix in Maven artifact names

Drop the code that removes SNAPSHOT suffix in artifact name. This prevents
Gitblit plugin from fetching its custom artifact from Gerritforge Maven
repository, making from the right name:

  com/gitblit/gitblit/1.4.0-SNAPSHOT/gitblit-1.4.0-SNAPSHOT.jar

the broken artifact name:

  com/gitblit/gitblit/1.4.0-SNAPSHOT/gitblit-1.4.0.jar
