preflight: replace idevice_event_* with thread safe implementation

idevice_event_subscribe() calls usbmuxd_subscribe() which will
start a thread waiting for device add/remove events. But this
implementation is not able to handle more than one "subscription".
However the preflight worker will start a thread for _each_ device
resulting in a really messed up situation if more than one device
is attached at the same time. This fix will use usbmuxd's internal
device_remove function calling a preflight callback to make this
implementation thread safe.
