Currently if the install_packages macro is run with an empty
package list, it will add a yum or apt-get command with no
packages listed.

This bug fix aims to omit this line when no packages have
been given, or, the operator wants to use the "_override" /
"_remove" functionality to disable all packages being
installed in a Dockerfile.
