[sr-dev] [kamailio/kamailio] rr: Add new return value for preloaded route set to loose_route() (#1830)

[Alex Hermann]

Instead of returning just -1 (error), return a dedicated value. Now it is
possible to detect from the script if a preloaded Route header was removed
that pointed at the local proxy.

The new return code is kept negative, so all code checking for failure response
keeps working.
