Bug#981084: dh-elpa should provide dh-sequence-elpa

[Helmut Grohne <helmut@subdivi.de>]

Package: dh-elpa
Version: 2.0.6
Tags: patch

Please provide dh-sequence-elpa. Doing so allows using it declaratively.
Instead of adding "--with elpa" to the dh invocation, one can then add
dh-sequence-elpa to Build-Depends. Using the dependency technique, use
of the addon can be restricted to indep-only builds by moving it to
Build-Depends-Indep. Also the sequence can be conditionalized using
build profiles. (Though using build profiles requires fixing #981014.)
