core: Comment testSourceDirectory in pom.xml to fix build

A clean build is breaking due to testSourceDirectory being enabled. The
tests in core/test/com/cloud/hypervisor/vmware/ depend on vmware nonoss
libs and utils's test classes.

The issue here is that core's test classes depend on utils's test
classes.

Commenting testSourceDirectory for now.

The following patch should be added when this issue is fixed, only if
VMWare related tests are moved from core/test:
