Linux: in printf cast uint64_t to unsigned long long

Browse Source 
When printing a uint64_t type using %llu, this works on a 32bit
system, but on a 64bit machine uint64_t is an unsigned long.

The compiler complains about unmatching types.

The time times in PX4 should likely have been unsigned long long
and not uint64_t as that type changes per architecture.
