Description of problem:
When sending traps on SNMP v3 using net-snmp-5.8-20 in RHEL 8.4, the engineTime value remains zero.
This is a problem as the receiving agent does not accept engineTime with a zero value, it expects engineTime and engineBoots values to progress.
snmptrap by default runs the code below to set session.engineBoots and session.engineTime for SNMP v3 traps (not inform).
session.engineBoots = 1;
if (session.engineTime == 0) /* not really correct, */
session.engineTime = get_uptime(); /* but it'll work. Sort of. */

Steps to Reproduce:

Unable to send SNMP traps.
Should be able to send SNMP traps.
Upstream patch is already in place for snmptrap binary. It resolves the issue by setting the library engineBoots and engineTime values before sending.
