When applying the SNMP app, the ConfigMap "snmpd-etc-config" was found
to refer to a non-existing directory.
This commit replaces references to /usr/lib64 with /usr/lib.
Additionally, it removes unused definitions.
Test plan:
PASS: Build stx-snmp docker image.
PASS: Install and configure snmp in a local environment.
Run kubectl get cm -n kube-system snmpd-etc-config -o yaml
and verify that this is using /usr/lib instead of /usr/lib64
