Adjusted file->sys_offset after the write() syscall. This fixes suboptimal behavior caused by surplus lseek() for sequential writes on systems without pwrite(). A consecutive read after write might result in an error on systems without pread() and pwrite(). Fortunately, at the moment there are no widely used systems without these syscalls.
