LU-17416 utils: option for lctl get_param to skip links

Added new --links and --no-links options for 'lctl get_param' and
'lctl list_param' to avoid following symlinks. Useful when combined
with a command like "lctl get_param -R '*'" which can dump a lot of
duplicate data due to symlinks under lov.*.target_obds and
lmv.*.target_obds pointing back to their respective osc.* and mdc.*
trees. By default --links is enabled to for lctl get_param to
continue to operate as it did before this patch.

Additionally, long options have been added for all previous options
in {list, get, set}_param to update command options to current
standards. This will also facilitate adding new options in the future
as well as code maintenance and readability.
