Fix broken tempest tests

This is step two to recover from Tempest failures. Fork is
deplorable, but this is a temporary fix until the extension
framework for L3 is put in place.

The fix is predicated on the fact that we can get to override
the l3 agent entry point reliably; alternatively the Tempest
job must explicitly call a 'new' forked L3 agent as stop-gap.
