Fix source distribution plan so that a source distribution build is tested correctly.

Building JIRA 4.4 from the source it has a transitive dependency on infinitydb which is not available publicly since its a proprietary library used by FishEye. Looking at the logs attached this comes from the com.atlassian.support:stp plugin.

A good fix would be to get said plugin to depend on FishEye's API instead (I believe it has one) or at least put an exclusion on the fisheye-jar for infinitydb:

  <exclusion>
    <groupId>com.boilerbay.infinitydb</groupId>
    <artifactId>infinitydb</artifactId>
  </exclusion>

Note: this is also a good workaround for anyone trying to build JIRA 4.4's from source.
