Subject: [PATCH] completion: Set standard style used by 'list-colors'

Set `LS_COLORS` if not already available so that it is available as
standard style `list-colors`.

This needs to be explicitly set in completion module to ensure that the
variable is available even if 'utility' module is not loaded earlier.
