YaGL: Modified the process state for the 64bit guest

If the guest image is 64bit, 'yagl_mem_get' function fails.
So the host yagl can not access the guest memory.
The failure occurs in the 'cpu_get_phys_page_debug'.
(<qemu>/target-i386.helper.c:820 if (env->hflags & HF_LMA_MASK))
Becuase the yagl process state does not have the flag like above,
it does not proceed as a normal routine in Ubuntu 64bit.
Therefore add the 'hflags' to the yagl process state.
