Fixes GCC 8 warning:
sdk/lib/3rdparty/zlib/contrib/minizip/zip.c:521:5: error: this 'for' clause does not guard... [-Werror=misleading-indentation]
     for (i=(int)uReadSize-3; (i--)>0;)
     ^~~
sdk/lib/3rdparty/zlib/contrib/minizip/zip.c:529:7: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the 'for'
       if (uPosFound!=0)
       ^~
