Statetrace: Make statetrace patch amd64 executables for true single stepping after system calls.
Because of peculiarities in how system calls are returned from, single stepping executes some system calls and the instruction following them in a single step. Statetrace now patches the executable image when it detects a system call to force "correct" behavior, aka the appearance of stepping one instruction every single time.
