Add PRI{u,x}limb for printf formats

This is to fix
```
src/Specific/Framework/bench/fibe.c: In function ‘fe_print’:
src/Specific/Framework/bench/fibe.c:130:5: warning: format ‘%llx’ expects argument of type ‘long long unsigned int’, but argument 2 has type ‘uint32_t’ [-Wformat=]
     printf("0x%016llx)<< %lu) + ", x[i], limb_weight_gaps[i-1]);
     ^
