MueLu: Consider allowing "long long" for Tpetra GO when building MueLu tutorial

[abodado]

When building Trilinos, I often see this message:

-- MueLu's tutorial requires for a correct build that if Tpetra is enabled, then GlobalOrdinal=int must be enabled, and either the Serial or OpenMP Nodes in Tpetra be enabled. Since this is not the case, I am disabling MueLu's tutorial by default. See Trilinos GitHub Issue #1726 for details: #1726
-- You chose to enable MueLu's tutorial, even though I told you that it may not build correctly. You are responsible for whatever build or link errors may occur as a result.

Not an urgent matter, but am curious if plausible to update the MueLu example source code to allow the tutorial to be built with "long long" GO for Tpetra, since "long long" is Tpetra's default GO.

@GrahamBenHarper @mayrmt Is this something that is going to be addressed by the tutorial update?

@jhux2 yes, the tutorial update will migrate all examples to Tpetra, so this should be easy to fix. Current behavior arises from the old Epetra examples.
