TT#37257 Improve installing of additional packages

Make a single list of all required packages.
For each package from the list check if it is installed or not.
Install all packages at once.
Remove custom source.list for these additional packages. Previously it
was used because GRML image and its default source.list were too old.
Now a new GRML is used so we have a vise-versa situation - deb.sipwise.com
contains older packages than default source.list so there is no sense to
use any custom locations and options.
