Bluetooth: Increase timeout for legacy pairing from 10 seconds to 40 seconds.
Legacy pairing is a bit of a problem because on the incoming end it is
impossible to know pairing has begun:

There are some mainline patches such as "Add different pairing timeout for
Legacy Pairing" but they do not address the HCI sequence above.
I think the real solution is to avoid using CreateBond(), and instead make
the profile connection immediately. This way both sides will use a longer
timeout because there is a higher level connection in progress, and we will
not end up with the useless HCI sequence above.
