test build: birt2.6.0 v20100224-0630

  can not launch birt junit test using birt-tests-suite-2_6_0-20100224.

  the test.xml in org.eclipse.birt.test_2.2.0 could not find file library.xml because the path of this file was wrong.

snippets of test.xml:

<property name="library-file" value="${eclipse-home}/plugins/org.eclipse.test_3.2.0/library.xml" />
fixed.
closed.
