[Fleet] fixed bug where installed beta integration was visible multip…

…le times (#150979)

## Summary

Fixes #150969

Filtering for only uploaded packages that are not in registry.
This fixes of bug of linux integration showing up multiple times when
the `/packages` call with `prerelease:false` and `prerelease:true`
options are quickly following each other.

To verify:
- Navigate to Integrations, search `linux`.
- Add linux integration to agent policy.
- Repeat the same process again.
- Navigate back to Integrations and search `linux`.
- Only one Linux metrics integration card should be visible.
