Update CameraStreamBuffering test case

CameraStreamBuffering test case intentionally calls
setMaxFramesInFight() with very large integer value to verify that API
handles unreasonaly large value properly.  A type of its parameter is
changed from unsigned 32-bit integer to signed 32-bit integer in the
latest EVS interface definition written in the stable AIDL.  To adapt a
test case, this CL updates it to use std::numeric_limits<int32_t>::max()
instead of 0xFFFFFFFF, which is translated as -1 in signed 32-bit integer
format.
