Julian Brost a55939e462 Override exit code on process timeout 
As Icinga first sends a SIGTERM to a check plugin on timeout to allow it to
terminate gracefully, this is not really part of the plugin API specification
and we cannot assume that plugins will handle this correctly and still exit
with an exit code that maps to UNKNOWN. Therefore, once Icinga decides to kill
a process, force its exit code to 128 to be sure the state will be UNKNOWN
after a timeout.
