openmpi: add missing libevent dependency

[valgur]

Summary

Changes to recipe: openmpi/[4.x]

Motivation

I'm splitting off the bugfix changes from the more general update PR #25162, which might take a while to get working. A follow-up to #18980.

The configure script in OpenMPI looks for libevent on the system and falls back to a vendored one if it's not found. Accidentally using the system version of libevent is unwanted and likely to break consuming projects and we also generally try to avoid vendored dependencies, if possible.

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
