UDPTL: Fix a regression where UDPTL won't load default settings

If the file udptl.conf is unavailable at startup, UDPTL will fail to
initialize and while it makes some noise, it isn't immediately
obvious why consumers start to fail when using it. This patch makes
UDPTL load as though an empty config was provided  when udptl is
unavailable at startup.
