[ptxdist] [PATCH 1/7] ptxdist: Add list-packages command

[Sascha Hauer <s.hauer@pengutronix.de>]

This adds a command to list all packages currently selected. ptxdist
gurus can use 'ptxdist print PACKAGES' for the same purpose, this command
is for the people who can't remember the command. As a bonus list-packages
prints one package per line and sorts them alphabetically.
