libdnet: fix for autoreconf error on Lion

Libdnet is used by snort, but the manual autoreconf statements
cause a build error on Lion.  This is likely due to some subtle
changes in autoconf-2.69.

* Remove manual autotools statements.
* Set `ACLOCAL` to include the `config` directory.
* Use `autoreconf -ivf` the way the `autoconf` docs recommend.
* Remove the unrecognized `--disable-debug` flag.

This compiles with or without the `--with-python` flag, and it
functions well in `snort` using all five compilers from XCode
4.3.2 and 4.0.2 on Lion and Snow Leopard.  It's interesting to
see software from 2007 build the python bindings and install
them into the HB site-packages correctly.

Fixes #12174
