Add a wait before sending via the 433MHz transmitter

Rather than immediately entering the lengthy (24ms+) loop to send a
command allow a number of calls to usbPoll() to complete first. This
allows the usbrelay control program to successfully receive a response
to its hid_write() call before we stop responding to USB for a bit.
