scripts/gen_archlist: use sets for manipulating keywords

Avoids logic like "if bla not in list then add it" when it is done by
sets already. Sorting can be applied when printing.

scripts/gen_archlist: rename do_not_want function

Give it a better name of split logic down in multiple lines, it is
easier to read that a kilometric if line.

Logic was inverted to avoid double negation in match_wanted_atoms
function.

scripts/gen_archlist: fix gen_cpv_kws to use arguments from command line

* Change the cpv_kw format to a tuple, there is no point in using a list.
* Move/edit some lines around to expose logic in a clearer way.
* Retrieve arguments from command line.
* Add some comments.

Could not figure out if this was needed at all. At least it appears it
is not useful anymore. Kill its weird logic with fire.

scripts/gen_archlist: Rename do_not_want function

Give it a better name of split logic down in multiple lines, it is
easier to read that a kilometric if line.

Logic was inverted to avoid double negation in match_wanted_atoms
function.
