/opt/bin/xochitl script issues

[Havner]

Describe the issue
2 small issues in the script:

1. The is-active function doesn't exist here
   https://github.com/toltec-dev/toltec/blob/stable/package/xochitl/xochitl#L24
2. The script masks non existing service (e.g. rm-sync):
   https://github.com/toltec-dev/toltec/blob/stable/package/xochitl/xochitl#L20C1-L22C3
   And nothing unmasks it when uninstalling as the unmask option have different conditions in the postremove:
   https://github.com/toltec-dev/toltec/blob/stable/package/xochitl/package#L110C1-L111C41

Not putting more info as this has been discussed in the discord and I think the code is clear enough to see the issues.
