The hex stream output helper was introduced in f391048a7b ("libcamera: utils:
Add hex stream output helper"). It simplifies writing hexadecimal values to an
ostream which can be used in this test too. As the helper doesn't modify the
stream configuration (refer to utils::hex() documentation), this eliminates the
need of restoring the stream's format state as pointed out by the coverity scan.
