added suites that maps to go packages to avoid test name collition

Hi, 
At least in bamboo, if you have 2 test with the same name in different packages they will count as one (because testsuite's names & testcase's classes where named go2xunit. I replaced that for package's full name. 
It works fine (in bamboo) but I guess it will also works in jenkings. 
it has test and is go formatted.
Regards.
