evtranalyze: %llu -> %ju, (uintmax_t)

[Nuno Antunes]

Hi all,

I tried to buildworld on x86_64 but evtranalyze would break the build.
I made a few simple changes to correct the warnings (that were being
treated as errors). I tested on i386 and it compiled as well. I did no
functional test though.

The patch is here:

I mostly replaced %llu by %ju and casted the respective printf
argument to (uintmax_t). The exception to this was in the sscanf,
where I used the PRI*/SCN* macros. Is there a better way to do this?

Cheers,
Nuno
