Change or test the path for the plugins directory

[nvogel]

With this version

http://www.monitoringexchange.org/attachment/download/Check-Plugins/Operating-Systems/Linux/check_munin_rrd/check_munin_rrd.pl

I've to change the line
use lib "/usr/lib/nagios/plugins" ;
with
use lib "/usr/local/nagios/libexec";

Maybe add a test to validate the path or make it dynamic because I lost a lot of time to figure out that.

Ah... assumptions... ;-)

Yep I should not expect the nagios plugin path to be there, instead of making that part dynamic, I'll try to fail earlier, ie try to include of fail.
