test-patch target not working on hudson.zones.apache.org due to HADOOP-3480

HADOOP-3480 has broken the test-patch target run by the Hudson Hadoop-Patch job. This is causing all patches to get a -1 on contrib testing.

Also, the message is very confusing now. This is what the console shows:

...
[exec] [junit] 08/06/26 14:34:57 INFO ipc.Server: IPC Server handler 9 on 44137: exiting
[exec]
[exec] BUILD SUCCESSFUL
[exec] Total time: 4 minutes 2 seconds
[exec] Some jars are not declared in the Eclipse project.
[exec]
...
[exec]
[exec] -1 contrib tests. The patch failed contrib unit tests.
[exec]
...

The -1 comes from the "Some jars are not declared in the Eclipse project" line which is a warning caused by HADOOP-3480. This needs to be improved.

The problem arises from the fact that additional jar files are copied into the lib/ directory for clover (code coverage), checkstyle, etc by the test-patch process on Hudson. Also, there are src/test/lib/ftp*.jar referenced in the ECLIPSE_DECLARED_JARS variable:

Brice, can you rework this?
