Scott Mansell 4fa3ddcbf6 CMake: Fix FindMiniupnpc for ubuntu 14.04
Ubuntu 14.04 has miniupnpc 1.6.3
REGEX was failing because the string was empty, causing cmake to
error and not generate a Makefile.

This allows systems with older versions of miniupnpc to fall back
to the statically linked version in externals.
