omnitrace -> omnitrace-instrument (#256)

* omnitrace-exe -> omnitrace-instrument

- Renamed omnitrace executable to omnitrace-instrument
- Provided dummy omnitrace exe which forwards onto omnitrace-instrument
- updated all docs to reflect the name change of the executable
  - however, it is possible some were missed

* Update dyninst submodule

- correctly handle BOOST_LINK_STATIC in DyninstBoost.cmake

* Disable IPO for omnitrace-instrument
