epoll: Use different epoll types for passt and pasta tap fds

Currently we have a single epoll event type for the "tap" fd, which could
be either a handle on a /dev/net/tun device (pasta) or a connected Unix
socket (passt).  However for the two modes we call different handler
functions.  Simplify this a little by using different epoll types and
dispatching directly to the correct handler function.
