Improve efficiency of lxc_ifname_alnum_case_sensitive
To detect if a newly generated interface name is a duplicate of an existing
interface lxc_ifname_alnum_case_sensitive() currently gets a list of all
interfaces using netns_getifaddrs(). When the system has a small number of
interfaces this works fine, however when there are thousands or tens of
thousands of interfaces this quickly becomes less than optimal.
As we only need to check if an interface name exists, and do not need the
detailed information about the interfaces provided by netns_getifaddrs(), we
can instead use the if_nametoindex() function, which is much more efficient.
