Change NDT init script to use $PATH variable when counting numer of running processes

Hi,

Problem that had me scratching my head for a while, with fix:

web100srv wouldn't start:
===
[root@ndt init.d]# ./ndt restart
Stopping web100srv:                                        [FAILED]
Stopping fakewww:                                          [  OK  ]
Starting fakewww:                                          [  OK  ]
===

Nothing in logs etc etc

Digging deeper
===
[root@ndt init.d]# sh -x ./ndt start
...
+ start_web100srv
++ ps auxw
++ grep web100srv
++ grep -v grep
++ wc -l
+ cnt=1
+ '[' 1 = 0 ']'
+ start_fakewww
+ '[' '!' 1 = 0 ']'
++ ps auxw
++ grep fakewww
++ grep -v grep
++ wc -l
+ cnt=0
+ '[' 0 = 0 ']'
+ echo -n 'Starting fakewww:'
Starting fakewww:+ /usr/sbin/fakewww -f /index.html -s -l 
/var/log/ndt/fakewww_access.log -e /var/log/ndt/fakewww_error.log
+ RETVAL=0
...
===
It doesn't even try to start web100srv

===
[root@ndt init.d]# ps auxw | grep web100srv
root      6930  0.0  0.0   3824   536 ?        S    Apr12   0:00 tail -f 
/var/log/ndt/web100srv.log
root     20412  0.0  0.0   4020   712 pts/1    R+   16:15   0:00 grep web100srv
===

Because I was doing a tail on web100srv.log, the web100srv program itself 
couldn't be restarted!
Heisenberg strikes again !!

Change the greps in /etc/init.d/ndt to include the bin path
===
   cnt=`ps auxw | grep $path/web100srv | grep -v grep | wc -l`
   cnt=`ps auxw | grep $path/fakewww | grep -v grep | wc -l`
===
and you can now tail the log file and restart the server
