fixed packages.list() assuming packages dir exists

This generally is fine, as the folder is created on startup... IF
Northstar is installed! And so, if you start Viper for the first time or
Viper as only just extracted/created the R2Northstar folder, then the
folder wont exist, but it'll simply assume as such.

Now we actually handle this correctly.
