Summary: check_mem.pl swaps used and free memory

Initial Comment:
The check_mem.pl script incorrectly pulls used and 
free memory from vmstat.  It's reversed.

The attached patch file fixes the problem.

Hi Dave,

thank you for your report. Unfortunately check_mem.pl is in the contrib
directory and therefore not actively maintained by the nagiosplug-devel
team.

check_mem.pl relies on the position of vmstat output which can change from
system to system or from release to release. On my suse 10.1 box, the total
was not even calculated correctly. Maybe you want to give the check_mem
plugin from nagiosExchange.org a try which relies on the `free` command.

Yet I reviewed your note and think changing it would break compatibility
for those users that might have been using it for long.

Sorry about that
Matthias
