elfutils: fix the num passed to memset in ar.c

Following build error will appear on Fedora18+:
ar.c: In function 'do_oper_delete':
ar.c:918:31: error: argument to 'sizeof' in 'memset' call is the same expression as the destination; did you mean to dereference it? [-Werror=sizeof-pointer-memaccess]
   memset (found, '\0', sizeof (found));
