Updated git submodules

Project: integration/packaging master 6860fd511ef652ee211ff215137d01fead43ef92

Require Java >=1.8 for RPMs, vs current >=1.7

All currently supported versions of ODL require Java 1.8, so make it a
hard requirement in the RPM spec file. Currently installs always happen
to pull down 1.8, but we should force it.
