Summary: check_procs: Behave properly on OpenVZ hardware nodes

Initial Comment:
In an OpenVZ virtual environment: If you run "check_procs" on the hardware node, it returns information about all process on the hardware node + all virtual containers. It should of course ignore the virtual containers, as you would have a seperate NRPE server running in these.

The attached patch solves this problem, by checking in /proc/PID/status if the process runs on the hardware node, or in one of the containers.

This new codepath simply does nothing on non-OpenVZ/non-Linux systems.

Patch against current master (check_procs v1.4.13.163.gb8a6.dirty)
Tested on Debian Linux 5.0 "lenny", running in 64-bit mode.

Thanks,
Lukas
