Funtrace - bug fix release

Bug fixes (mainly the recording of the process address space was incorrect in a way that occasionally precluded decoding of function addresses to names / file:line)

After unzipping, run ./simple-example/build.sh and then ./simple-example/run.sh, see README.md (the "Trying funtrace" section) for troubleshooting (eg no -fxray-shared flag in clang, or ftrace permission issues) and what to do next.
