os-posix: Add os_set_daemonize()
The daemonizing functions in os-posix (os_daemonize() and os_setup_post()) only daemonize the process if the static `daemonize` variable is set. Right now, it can only be set by os_parse_cmd_args(). In order to use os_daemonize() and os_setup_post() from the storage daemon to have it be daemonized, we need some other way to set this `daemonize` variable, because I would rather not tap into the system emulator's arg-parsing code. Therefore, this patch adds an os_set_daemonize() function, which will return an error on os-win32 (because daemonizing is not supported there).
