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.

#include <stdarg.h>

extern void putchar();

int
vprintf(fmt, ap)
	char *fmt;
	va_list ap;
{
	return(_doprnt(fmt, ap, &putchar));
}
