sensor-hal-sensorhub: fix the bug caused by static member variable

- static member variable has to be declared for using it.
  strangely std::vector variable is always okay regardless of a compile
  order if it is declared once anywhere. but std::map is not okay.
  dlopen() invokes the segmentation error when std::map variable is used.
  but if compile file order is changed, it doesn't have problem....
- because the problem about initializing static member variable, it is
  issued. so this patch just changes manager/controller to singleton class
  for removing the code that use static variables.
- now it is fixed.
