Accumulation of cf-agent processes due to locking on CFEngine tcdb lock file

Description
Sometimes, agents get stuck because they all try to lock /var/rudder/cfengine-community/state/cf_lock.tcdb.lock, resulting in a deadlock
In #3928, we implemented a workaround based on the number of agent running, to kill them all if necessary, but here we'll check the age of
/var/rudder/cfengine_community/last_successful_inputs_update
If it is older than 10 minutes, then the agent is stuck, and we kill the .lock file
It happens mainly with cfengine 3.5.x, so targeting to Rudder 2.8

A syntax error in the script prevent installation of rudder-agent:
/opt/rudder/bin/check-rudder-agent: 68: Syntax error: "elif" unexpected
Setting up rudder-inventory-ldap (2.8.3~rc1~git201402240715-squeeze0) ...
dpkg: error processing rudder-agent (--configure):
subprocess installed post-installation script returned error exit status 2
If block needs a command before elif and there is not. adding ':' ("do nothing" in bash, alias to 'true') fix the issue
