iproute/iprule: support toolchains without RTA_TABLE routing attribute
iproute.c: In function 'print_route':
iproute.c:85:9: error: 'RTA_TABLE' undeclared (first use in this function)
iproute.c:85:9: note: each undeclared identifier is reported only once for each function it appears in
iproute.c: In function 'iproute_modify':
iproute.c:467:36: error: 'RTA_TABLE' undeclared (first use in this function)
Fix it by partially #ifdef'ing the code added in b42107f21538e39d9a344376372f8261aed589b2
