Fix compilation of embench
...
The separation did not work before, somehow.
The new approach of redefining the function names, while hacky, definitely works though.

Move install nyx functionality from build script to runtime
...
It did not make a lot of sense to have that in the buildscript, as that will make nyx_runner dependent on the target directory.
This also allows specifying a binary to trace at runtime

Use correct conversion for time values
...
Two errors I made:
* cycle durations are not constant, their value relies on the cbr
* tsc frequency was not exactly 2.7Ghz, now calculated at runtime

Track total time using tsc packets and total internal time with cycles.

Something is still wrong though, the tsc time is somehow less than the cyc time
