Get ifaces for udev rule use

In case BOOTIF is not set and IFACES are not set in bonding/vlan/bridge code,
net-genrule.sh will fall to bring up all net interfaces.

Here add a failsafe option to read IFACES from /tmp/net.ifaces

[v1->v2]: move IFACES reading from net.ifaces after bonding/vlan/bridge info
code chunks.
[v2->v3]: [ -n "$IFACES" ] should be  [ -z "$IFACES" ]
