test programs: use printf %d format for codec parameters
Even though all codec params (both FR and EFR) are small unsigned integers,
we use signed int16_t data type for both, for interface reasons: in the
case of FR it's the gsm_signal type of libgsm, and in the case of EFR
it's the Word16 type of ETSI codec guts. Therefore, the correct printf
format is %d, not %u, when the objective is to see what's in the variables
(what the compiler sees) and catch any bugs.
