[armadillo] Make primary CMake target armadillo::armadillo and reduce…

… aliases

* Make armadillo::armadillo the primary CMake target because the
  upstream CMake module doesn't enforce this behaviour, and the policy
  of CCI is to use packagename::packagename when no target is enforced
* Make Armadillo::Armadillo and armadillo CMake target aliases as these
  are common in the wild, and this will facilitate conan package
  compatibility with existing build scripts.
* Remove Armadillo::armadillo and Armadillo as CMake targets as these
  have not been observed in the wild.
