Maintain granularity in cpu data
...
Export cpu mode times as original uint64_t data,
and update frequency, and do the conversion to
float64 and subsequent division in go.

Remove old freq finding code
...
This is the code that was lifted from the freebsd
implementation, but was not correct.

Use correct frequency for calculating cpu time
...
The correct frequency is the systimer frequency,
not the stathz.
From one of the DragonFly developers:
The bump upon each statclock is:
((cur_systimer - prev_systimer) * systimer_freq) >> 32
systimer_freq can be extracted from following
sysctl in userspace:
sysctl kern.cputimer.freq

...
Duplication was caused by malloc returning a
region of memory that already had data in it.

Correctly exporting values
...
Moved to exporting via a string, which is then
split and parsed.
The string is sometimes duplicated, however.
