Description of problem:
chekc_icmp plugin has no suid bit set and therefore it is not work. Icmp packets
root privileges are required and nagios server is running under "nagios" user.

Version-Release number of selected component (if applicable):
nagios-plugins-icmp-1.4.3-18.fc5

How reproducible:
always

Steps to Reproduce:
try to use check_icmp as non root user, for example:
1.su nagios 
2./usr/lib/nagios/plugins/check_icmp localhost
  
Actual results:
check_icmp: Failed to obtain ICMP socket: Operation not permitted


Expected results:
OK - localhost: rta 0.210ms, lost 0%|rta=0.210ms;200.000;500.000;0; pl=0%;40;80;;


Additional info:
It is not an security disadvantage, because any user, which don't require
check_icmp plugin can uninstall them.
I have an yum plugin to fix this bug and it is not important for me, but may be
important for other users.
I am using check_icmp instead of check_ping, becaus it has been hard to set
proper selinux permissions for check_ping.
