gsm0408_test: add unittest for gsm_gsmtime2fn()
The function gsm_gsmtime2fn(), which is used to compute a frame number
value from given starting time values T1, T2 and T3 has no unit test.
Due to to the modulo that is used the computation can be a bit tricky.
Lets add a unit-test to make sure the function works as expected.
