They are not added because they are not needed for the skeleton package.
You can eiher write them by hand -- 461 CRAN packages using Rcpp provide
examples -- or use a different generator:
R> library(RcppArmadillo)
R> RcppArmadillo.package.skeleton("youssef")
Calling kitten to create basic package.
Creating directories ...
Creating DESCRIPTION ...
Creating NAMESPACE ...
Creating Read-and-delete-me ...
Saving functions and data ...
Making help files ...
Done.
Further steps are described in './youssef/Read-and-delete-me'.
Adding pkgKitten overrides.
Deleted 'Read-and-delete-me'.
Done.
Consider reading the documentation for all the packaging details.
A good start is the 'Writing R Extensions' manual.
And run 'R CMD check'. Run it frequently. And think of those kittens.

You could always remove the LinkingTo: etc for RcppArmadillo if you don't
need Armadillo ...
Also see the excellent "Writing R Extensions" manual, Section 1.2.4 entitled
"Using C++11 code" about another way of setting C++11 via DESCRIPTION:
Packages without a 'Makevars' file may specify that they require
C++11 by including 'C++11' in the 'SystemRequirements' field of the
'DESCRIPTION' file, e.g.
SystemRequirements: C++11
