    Don't use wingenminiupnpcstrings when generating miniupnpcstrings.h

    The wingenminiupnpcstrings tool is used on Windows to generate version
    information. This information is irrelevant for us, and trying to use
    wingenminiupnpcstrings would cause builds to fail, so just don't use it.

    We should be able to drop this once we are using 2.1 or later. See
    upstream commit: 9663c55c61408fdcc39a82987d2243f816b22932.
