Use rpm instead of repoquery for is_installed()

* This keeps us from hitting bugs in repoquery/yum plugins in certain
  instances (#2559).

* The previous is also a small performance boost

* Also in is_installed(), when using the yum API, return if we detect
  a package name has been installed.  We don't need to also check
  virtual provides in that case.  This is another small performance
  boost.

* Sort the list of packages returned by the list parameter.
