libxtables: define xtables_free_opts()

Introduce xtables_free_opts() an xtables variant of
free_opts() which uses xtables_globals already set
by xtables_set_params(). The end goal is to have all internal
references in xtables.c use xtables_free_opts() instead of
depending on external defined free_opts()
