Chef::Provider::Package#package_names_for_targets

Returns the package names which need to be modified.  If the resource was called with an array of packages
then this will return an array of packages to update (may have 0 or 1 entries).  If the resource was called
with a non-array package_name to manage then this will return a string rather than an Array.  The output
of this is meant to be fed into subclass interfaces to install/upgrade packages and not all of them are
Array-aware.
