[CCID3]: Remove build warnings for 64bit

This clears the following sparc64 build warnings:
 1) warning: format "%ld" expects type "long int", but argument 3 has type "suseconds_t"
 2) warning: format "%llu" expects type "long long unsigned int", but argument 3 has type "__u64"
Fixed by using typecast to unsigned. This is argued to be safe, since the quantities, after
de-scaling (factor 2^6) fit all in u32.
