cp2k: fixed compilation issues for intel stack

Added DFLAGS to the `make.inc` file being written.
These macros are also added to the language specific variables
like CFLAGS, CXXFLAGS and FCFLAGS. Changed `spec.satisfies('foo')`
with `'foo' in spec` in `intel-mkl`, see #4135. Added a basic
build interface to `intel-mpi`.
