Summary: check_snmp buffer overflow when parsing snmpget replies

Initial Comment:
I have found a buffer overflow in check_snmp. It copies to the perfstr char array from snmpget replies without checking if it grows too big, which is somewhere around 17,000 characters on my system.

I have attached a patch that corrects this problem.
