Sort lint_groups in no_lint_suggestion

The no_lint_suggestion routine passes a vector of lint group names
to find_best_match_for_name.  That routine depends on the sort
order of its input vector, which matters in case multiple inputs
are at the same Levenshtein distance to the target name.

However, no_lint_suggestion currently just passes lint_groups.keys()
as input vector - this is sorted in hash value order, which is not
guaranteed to be stable, and in fact differs between big- and
little-endian host platforms, causing test failures on s390x.

To fix this, always sort the lint groups before using their names
as input to find_best_match_for_name.  In addition, deprecated
lint groups should never be suggested, so filter those out.
