staticd: Allow table_id to be a distinguisher for installation

Browse source 
The table_id should be a discriminator in the installation of
static routes into zebra from staticd.  Add this to allow the end
user to do something like this:

ip route 4.5.6.7/32 192.168.209.44
ip route 4.5.6.7/32 192.168.209.44 table 3000
ip route 4.5.6.7/32 192.168.209.45 table 3000

robot# show ip route
Codes: K - kernel route, C - connected, S - static, R - RIP,
       O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP,
       T - Table, v - VNC, V - VNC-Direct, A - Babel, D - SHARP,
       F - PBR, f - OpenFabric,
       > - selected route, * - FIB route
