cleanup: Move init_random_seed() to where it is being used

The init_random_seed() function is only used by the init_static() in
init.c.  As this function was pretty basic and it is only being called
once, it was merged into init_static() instead of keeping it as a separate
function.

(I agree that calling functions often makes the code more readable, but
I would rather see that as a part of cleaning up the whole init_static()
function - in fact when moving all "unit tests" in init_static() to cmocka,
it will not be too bad in the end.)
