Patches harness/nbi/.common/common.xml from NetBeans version 7.1.
Proposed patch changes exec task in common.xml to ant task. This makes installer building independent of external execution and therefore more portable.
This patch as well as patch proposed in http://netbeans.org/bugzilla/show_bug.cgi?id=207518 are needed in order to integrate installers building into nbm-maven-plugin.
