network-ups-tools: update to 2.8.4

[slymattz]

Testing the changes

• I tested the changes in this PR: YES After installing the network-ups-tools package and rebooting, I checked two things:
• [x] upsc myups@localhost (proper information about the UPS was output)
• [x] upsmon -c fsd (a forced shutdown was performed without any issues)

EDIT 12/8/25: resolved base conflicts

Local build testing

• I built this PR locally for my native architecture: x86_64-glibc

This PR is still relevant. I used git pull --rebase upstream master to keep my branch up to date with master. I also amended sha256sum hash as for some reason it had changed in the meantime.

I tested the package the same way I'd described in the original post. Both upsc myups@localhost and upsmon -c fsd did what they were supposed to.
