curses: don't initialize curses when qemu is daemonized
Current qemu initializes curses even if -daemonize option is passed. This cause problem because shell prompt appears without calling endwin(). This patch adds new function, is_daemonized(), to OS dependent code. With this function, curses_display_init() can check that qemu is daemonized or not. If daemonized, curses_display_init() isn't called and the problem is avoided. Of course, -daemonize && -curses doesn't make sense. Users shouldn't pass the arguments at the same time. But the problem is very painful because Ctrl-C cannot be delivered to the terminal.
