Hardware key: Enable single tap rebinding for hwkey back and home

Initially, this policy was put in place to safeguard
the UX by preventing a usecase where the device could
be put in a state without back or home available. However,
if a user puts the device in this state, it is easy enough
to navigate to button settings to fix it
