Replace %Lu with standard %llu

Browse Source 
Multiple scanf()s use the GNU-permitted %Lu. This is not supported in
other libraries and isn't to the POSIX specification. The L modifier
is only used for floats in POSIX.

Replacing %Lu with %llu is the same for GNU libc (scanf(3) says as much)
but means other libraries will work fine.

From master commit da715e3
