[sosreport] add separator argument to _format_list()

The _format_list() function handles formatting lists as comma-
separated strings, including line wrapping and indentation to
match an outer indentation level.

Add a new 'sep' parameter to allow the list to be separated by
an arbitrary character sequence.

This allows space-separated command line option lists to be
printed by --list-presets.
