Fix compile error against miniupnpc-1.6 when --enable-upnp

Browse Source 
The bump from miniupnpc-1.5 to 1.6 changes the definition of
two functions used by tor-fw-helper-upnp.c, upnpDiscover() and
UPNP_AddPortMapping().  This patch addresses this and adds a
check in configure.in for backwards compatibility.

Thanks to Nickolay Kolchin-Semyonov for some hints.
