server: check interface names in RPC arguments for validity
This patch introduces a method isIfaceName that checks interface
names from various RPCs for validity before e.g. using them as
part of iptables arguments or in filenames.
All of these RPC calls can only be called from applications
with at least the CONNECTIVITY_INTERNAL permission in recent
Android versions, so the impact of the missing checks luckily
isn't very high.
