upstream compat test complains about phosh-service

[14:38:52] Increase 'postmarketos-ui-phosh' pkgrel (6 -> 7), missing depend(s): phosh-service

The phosh-service package is intentionally not in pmaports master and v24.06, as it is a systemd package. Once we have the split repository (https://gitlab.com/postmarketOS/pmbootstrap/-/issues/2328), it will be added.

Let's add a workaround so the upstream-compat test isn't red until then.

Looks like this needs to be adjusted in pkgrel_bump.py in pmbootstrap.

I'll try to get to this over the next days, currently doing v24.06 bringup.
