CL:2559262 changed GetAvailableTransports() to unconditionally include
FidoTransportProtocol::kInternal in its result, which causes a platform
authenticator discovery to be instantiated. Prior to that CL no
discovery would be instantiated if IsUVPAA() returned false.

This causes a platform authenticator to be instantiated mistakenly when
the system/u2fd IsUVPAA() call is true, but Chrome's IsUVPAA() is false
due to being in an Off-The-Record context.

To work around this, explicitly check for OTR in
GetAvailableTransports(). This is temporary, until the CrOS platform
authenticator is enabled in Incognito (crbug.com/1157651).
