Update referential integrity config for DS 1.3.3

Hisorically DS provided defaults for the referential
integrity plugin in nsslapd-pluginArg*:

    nsslapd-pluginarg3: member
    nsslapd-pluginarg4: uniquemember
    nsslapd-pluginarg5: owner
    nsslapd-pluginarg6: seeAlso

In 389-ds 1.3.3, the multi-valued referint-membership-attr
is used instead.

The old way still works, but it requires that the values
are numbered consecutively, so IPA's defaults that started
with 7 were not taken into account.

Convert IPA defaults to use referint-membership-attr.
