fixed bug when check_procs is used

When using check_procs, the sendNscaWrapper.sh is not able to find the right extScript. This happens, because the "command -v" call returns more than one executeable and the exit code 1. Not sure if my solution is very elegant, but it works.

./sendNscaWrapper.sh -d "/usr/lib/nagios/plugins/check_procs -C cron -w 1:100 -c 2:100" 127.0.0.1 CRON
