tests: updated names for the kernel tests

After run Sanitycheck script I found out that test cases
had the same test case name in the test result .xml file.
For board itodk in .xml file was duplicated kernel.common test.
To get rid of it, I decided to change test cases names
for the kernel tests, contained name kernel.common.
Now only one test has kernel.common test name,
and will be no duplicated test cases names in the future.
