Calling Sys_Dirname on argv[0] lead to slashes in argv[0] getting overwritten on Linux (and potentially other non-Windows platforms), causing some external script to fail sending signals to the right process, because the path changed.
This pull request adjusts Sys_Dirname and Sys_Basename to work with a copy of the given string instead of the original. This makes the behavior of both functions more consistent between Windows and other platforms.
