Fix OOT builds with swig files in source dir
Fix OOT builds with swig files in source dir

Normally, when the Makefile calls swig, the resulting files end up in the build
directory. However, when the files are pre-generated (e.g. as in the znc 1.0
tarball) and an out of tree build is used, they are in the source directory and
installation fails.

Thanks to Kinji for reporting this.
