There is no format checking for the variadic functions that use printing inside kselftest.h. Because of this the compiler won't be able to catch instances of mismatched printf formats and debugging tests might be more difficult. Add the common __printf attribute macro to kselftest.h. Add __printf attribute to every function using formatted printing with variadic arguments.
