Fix JAR manifest claiming it is Commons IO project

Buck has one annoying "feature": java_binary rule merges manifest entries
from dependent JARs unless input JAR possesses these entries itself [1].

Repication plugin suffers from this "feature" because this is the only core
plugin that depends on another library: Apache common-io library.

Showing the documentation for replication plugin reveals that it was written
by Apache Software Foundation and is called "Commons IO" [2]:

Name	Commons IO
Vendor	The Apache Software Foundation
Version	v2.8
