Update git submodules

* Update docs/submodules/releng/builder from branch 'master'
  to d5e8f75a9f0db5fcc780d7d0157234a17dd20356
  - Merge "Increase timeout for jjb jobs to 60"
  - Increase timeout for jjb jobs to 60

    builder-merge regularly fails with a 30 minute timeout in ODL if the
    job needs to delete things. This is due to the size of ODL's jjb
    configuration so let's bump it to 60 to give it more time to
    complete.
