    extend libfetch test to detect incompatible implementation; rel 2
    
    fetchGetURL in libfetch from FreeBSD returns FILE* and that's what zfs
    expects. fetchGetURL in libfetch from NetBSD (used in PLD) returns
    fetchIO*. this incompatibility is not caught though and unfortunately
    it's not possible to select libfetch implementation explicitly.
