qualify internal namespace with dealii::

Fix errors like:

/src/include/deal.II/lac/la_vector.templates.h:196:5: error: no member
named 'VectorOperations' in namespace 'dealii::LinearAlgebra::internal';
did you mean 'VectorOperation'? [clang-diagnostic-error]

that appear if some other internal namespace is included before
la_vector.templates.h

part of #9933
