check_nt - MEMORY USAGE - incorrect results

[C. Bensend]

Not entirely accurate.

I just started troubleshooting a Win2008 R2 system yesterday - it has
16GB of physical RAM + 16 GB pagefile for a total of 32GB of virtual
memory.

The system is using 10.9GB of physical RAM, yet check_nt tells me
it's using 2.69GB.  Completely wrong, even if check_nt was only
talking about physical, only talking about virtual, or talking about
the sum.

Solution?  Remove yet another checkcommand using that outdated
program.
