perf tools: Fix build dependency of perf python extension
The perf python extention (perf.so) file lacks its dependencies in the Makefile so that it cannot be refreshed if one of source files it depends is changed. Fix it by putting them in a separate file and processing it in both of Makefile and setup.py.
