sms-pdu-decode family: fix VP-Relative header spacing When VP-Relative is small enough to be reckoned in 5 min or 30 min units, it was printed incorrectly, with a cosmetic defect of one extra space. Fix this bug.

main()
{
	printf("Hello-world demo app (fixed UART version) running\n");
	for (;;) {
		putchar('=');
		if (command_entry())
			command_dispatch();
	}
}
