ClatdController - iptables drop including interface name

This is a very minor bug fix.  Technically we could have duplicate
src/dst ip's on different interfaces and then we'd end up with the second
add failing and the first remove succeeding and there being nothing left
for the second remove...

Test: atest bpf_module_test clatd_test libbpf_android_test libnetdbpf_test
