Update git submodules

* Update docs/submodules/sfc from branch 'master'
  - Bug fix: Do not start testing before checking

    JIRA:SFC-113

    We used to check that the ACL and RSP flows were implemented because it took a
    lot of time. However, the new ODL Nitrogen reduced this time a lot and thus we
    must check that the vxlan_tool is up and the HTTP port is up in the server
    before doing any test
