Your problem is not in setting root permission, but in trying to do something that root permission does not directly enable, such as writing to a read-only file system. To do that your program will have to remount the filesystem read/write, or you will have to change the system startup scripts to make it writeable by default.
Why particularly do you need to write to /system anyway? Or was that just a poorly chosen test case?
