EclipseWriter: work around a GCC 4.4 smart_ptr bug

maybe it is not a bug but a slightly spec. The problem is that GCC 4.4
does not implicitly convert std::shared_ptr<$FOO> to
std::shared_ptr<const $FOO> which caused the recent Jenkins build
errors at Statoil. Note that this problem only occurs with the output
writer in conjunction with the old Eclipse parser, so
OPM/opm-autodiff#105 also makes the problem disappear. The present
patch addresses the root cause, though...
Fixed test_linearsolver for the official 2.2 release.

This release does neither support KAMG nor FastAMG. Therfore

Fixes the laplacian.

As we do not represent dofs on the boundary, we need to make sure that all diagonal
values are 4.
Increase verbosity such that we see the actual solve
