check_procs: Ignore ENOENT when checking for myself

Browse source 
Previously, when a process exited between the call to /bin/ps and
stat("/proc/his/exe") was exiting it was not considered as possible
instance of check_procs. This commit makes check_procs ignore all
processes where /proc/pid/exe does not exist.
