Bump Pyroute2 version to 0.5.5

Pyroute2 is modifying the default logger, adding NullHandler to it. If
the logger is not properly configured, like in any service or agent
spawn in Neutron, the only handler will be NullHandler. This prevents
from rendering the message passed, as when StreamHandler is used.

This issue is present only in version 0.5.4 and 0.5.5. Current Pyroute2
master version implements a new logger which removes this problem.
