added cli_lsa_enum_account_rights() call. Note that this is in
principal similar to the existing cli_lsa_enum_privsaccount() call,
except that cli_lsa_enum_account_rights() doesn't require a call to
open_account first. There is also the minor matter that
cli_lsa_enum_account_rights() works whereas
cli_lsa_enum_privsaccount() doesn't!

this call can be used to find what privileges an account or group
has. This is a first step towards proper privileges support in Samba.
