New issue by nvkomimi on void-packages repository

https://github.com/void-linux/void-packages/issues/44993

Description:
### Is this a new report?

Yes

### System Info

Void 6.3.12_1 x86_64 GenuineIntel uptodate rFFFF

### Package(s) Affected

libwacom-2.7.0_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

tablet should be fully usable

### Actual behaviour

after libwacom configuring, it seems to be detected in gnome control center, however I can't "test" it and no apps can grab the stylus input
the buttons work even without any configuration but that's kind of useless if the stylus can't be used

the device has 2 events in libinput, one of the buttons and one for the mouse/stylus movement
recording the mouse/stylus event shows that the input indeed works

configuring libwacom to see this tablet doesn't yield desired results but allows gnome to see and "configure" the tablet

libwacom suggests to use the utility for updating hwdb, however this seems to be dependant on systemd as this is the output
```
# libwacom-update-db

New hwdb file: /lib/udev/hwdb.d/66-libwacom.hwdb
Unable to find udev base directory: [Errno 2] No such file or directory: 'systemd-hwdb'
```

I also made an issue in libwacom's repo but I'm not even sure which package is responsible, I don't own any other tablets and haven't tested other distributions yet 
(though there are a lot of driver options available for the other distributions that say they support my specific tablet - Huion H610X)

### Steps to reproduce

1. configure a custom tablet for libwacom
2. use the utility for updating db
3. utility errors out in the end
