* refactor: duplicated path helpers into common/path.hpp

* update rocprof-sys-instrument to use shared path utility

* Add path::realpath(std::string[, std::string*]) helper function in common/path.hpp for binaries

* common: centralize remove_env implementation in environment.hpp

* remove unused includes from rocprof-sys binaries and argparse

* changing set to unordered_set wherever sorting is not required and additional cleanup

* review comment incorporated
