When doing a private install of DUNE libraries, the dune.module file
is put in the lib/ directory, regardless of architecture.
This patch searches the lib/ directory as a catch-all after having
searched the platform-specific directories. This should minimize the
chance of hitting an accidentally unrelated dune.module.
If the library is found, but dune.module is not, we really should give
an error because the #ifdefs in the code will not work as intended.
Print the locations where we expect the library to appear to the console
for better tracking.
As of 2013-09 the DUNE code that reads dune.module is not MultiArch-
aware. Thus, for a 64-bit platform it will look in lib/ on Debian and
lib64/ on RHEL.

The previous version may have ended up in lib64/ instead of lib/;
now we remove the arch-specific suffix from the path, and always
use the no-arch version.
Figure out where the closest dune.module is, and parse it for
information. The defines are added to config.h, so that our code
may behave differently for various versions available.
It actually works for opm-core 1.0 as well, but don't tell anyone;
we rather want people to use opm/core/version.h instead.
If a module has been backported and installed to a directory which
also contains the version number, e.g. /usr/include/dune-2.3, to
avoid clashing with an existing version in /usr/include, then this
part is now stripped from the include directory and added back to
the lib directory where we are looking for dune.module
