PPP, PPPoE: fix build when PPPOE_SCNAME_SUPPORT is defined

Browse Source 
lwip/src/netif/ppp/pppoe.c:768:24: error: pointer targets in passing argument 1 of ‘strlen’ differ in signedness [-Werror=poin$
     l1 = (int)strlen(sc->sc_service_name);
lwip/src/netif/ppp/pppoe.c:772:24: error: pointer targets in passing argument 1 of ‘strlen’ differ in signedness [-Werror=poin$
     l2 = (int)strlen(sc->sc_concentrator_name);

sc->sc_service_name and sc->sc_concentrator_name are best defined as
char* because there are passed to libc strings functions which expect
a char*.
