[ARM] Grafana agent fails on c6g AWS node

[phvalguima]

Bug Description

Testing the COS integration with Postgresql on ARM and I am seeing the grafana-agent subordinate failing with: https://pastebin.ubuntu.com/p/vXdhDv6HQb/

Juju status: https://pastebin.ubuntu.com/p/Qv7gSSz26M/
Checking if the actual lib file is there: https://pastebin.ubuntu.com/p/vVQMknxXNS/

This issue is not the same as #30 as we are using it all with [email protected].

Some of the discussions happened already in matrix

To Reproduce

juju deploy postgresql --channel=14/edge --constraints="arch=arm64 instance-type=c6g.xlarge root-disk=100G"
juju deploy grafana-agent --channel="latest/edge"
juju relate postgresql grafana-agent

Environment

AWS + Juju 3.4.2 and ARM CPU for postgresql & grafana-agent

Relevant log output

Full logs of the deployment: https://pastebin.canonical.com/p/hKfB8KzKwR/

This looks like a result of a mismatch in bases. Juju is currently unable to correctly resolve which charm to use based on the principal's base. Below you'll find a table fetched through charmcraft status grafana-agent that shows which revision to use for which base.
