sd-rtnl: introduce new API to set the NL header flags

Browse Source 
By default we set as NLM_F_CREATE | NLM_F_EXCL in
sd_rtnl_message_new_link
But incase of bridge we need to set NLM_F_REQUEST | NLM_F_ACK.

If NLM_F_EXCL is set then we are unable to set the parameters. As bridge
supports setting properties after creation not during creation.
