Allow overlap in resolv uid => DNS iface mapping

When multiple rules exist covering a given uid the one added most
recently will be used.

This allows us to handle the simultaneous tuns case where a new tun is
coming online for an already running VPN.

_resolv_clear_iface_for_uid_range now also takes the iface and removes
only that matching (iface, uid range) entry.

Fix pthread_detach for already-exited threads.

This fix handles the case when pthread_detach is
called for threads which have already exited.
This is required to avoid any memory leak
