CHANGES: snmpd: Fixed monitoring based on non-delta trigger.

snmpd crashed wit following snmpd.conf:
    monitor -s -D -r 10 -e LOGMATCH -o logMatchCurrentCount "Log Match" != logMatchCurrentCount
    logmatch LoginFailure1 /var/log/secure 10 su: .*fail.*

The reason was unitialized variable sysUT_var in mteTrigger_run(), it was
filled only if the trigger was delta-valued, while its value was used for all
triggers.

With this patch, sysUT_var is filled for all code branches where it is needed.
