Fix streamid print in examples to make clear it is hex

[SebastianSchildt]

Before

./acf-can-talker -i mon2 -d 16:93:3e:b3:5d:07 --canif vcan0 --stream-id=3735928559 --fd
acf-talker-configuration:
	Using NTSCF
	Using CAN FD interface: vcan0
	Using Ethernet
	Network Interface: mon2
	Destination MAC Address: 16:93:3e:b3:5d:07
	Talker Stream ID: 3735928559
	Number of ACF messages per AVTP frame in talker stream: 1

after

./acf-can-talker -i mon2 -d 16:93:3e:b3:5d:07 --canif vcan0 --stream-id=3735928559 --fd
...
	Talker Stream ID: 0x3735928559
...

which is better, because in the example the actual stream id is 237121996121 (0x3735928559)

Looks good. Fixed similar issue for Zephyr acf-can-bridge.
