selftests/tc-testing: sfq: check perturb timer values 



Add one test to check that the kernel rejects a negative perturb timer.

Add a second test checking that the kernel rejects
a too big perturb timer.

All test results:

1..2
ok 1 cdc1 - Check that a negative perturb timer is rejected
ok 2 a9f0 - Check that a too big perturb timer is rejected
