gnu: maths: dune-*: Update to version 2.7

* gnu/packages/maths.scm (dune-*): Update to version 2.7.
(dune-uggrid)[source] Download from Git, as no release tarball for
version 2.7 exists.
(dune-alugrid,dune-subgrid,dune-pdelab)[source] Use commit hashes as no
tags for version 2.7 exist (yet?).
(dune-istl)[source](patches) Add patch required to build version 2.7
without openmpi.
* gnu/packages/patches/dune-istl-2.7-fix-non-mpi-tests.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.

+Subject: [PATCH] make tests succeed when MPI is disabled
+
+When MPI is not available or explicitly disabled with the CMake build
+option -DCMAKE_IDSABLE_FIND_PACKAGE_MPI=TRUE, some tests were unable to
+build.
+
+The tests created from solverfactorytest.cc.in and part of
+scalarproductstest.cc use Dune::OwnerOverlapCopyCommunication which is
+defined behind `#if HAVE_MPI` and is thus not available in a non-MPI
+build. I've thus disabled those tests when MPI is unavailable.
+
+The matrixmarkettest did not work without MPI, as it contained some code
+using the wrong template parameters when HAVE_MPI was not set. Those
+template paramters have been fixed now.
+
+I've confirmed, that after my changes `make build_tests` succeeds to
+build all tests and that those tests run without failure.
