plasma5Package.baloo: Unbreak kde-baloo.service startup

Browse source 
https://invent.kde.org/frameworks/baloo/-/blob/048edc5d/src/file/kde-baloo.service.in#L9
expects the `kde-systemd-start-condition` executable to be in "baloo"s
installation directory, but unique nixpkgs derivations break this
assumption:

```
$ journalctl --user -u kde-baloo -o cat
Starting Baloo File Indexer Daemon...
kde-baloo.service: Failed to locate executable /nix/store/74g3ahh0k0x6d5rj5rxs1lxhzx81vgdd-baloo-5.95.0/bin/kde-systemd-start-condition: No such file or directory
kde-baloo.service: Failed at step EXEC spawning /nix/store/74g3ahh0k0x6d5rj5rxs1lxhzx81vgdd-baloo-5.95.0/bin/kde-systemd-start-condition: No such file or directory
kde-baloo.service: Skipped due to 'exec-condition'.
Condition check resulted in Baloo File Indexer Daemon being skipped.
```
```
$ systemctl --user cat kde-baloo | grep kde-systemd-start-condition
ExecCondition=/nix/store/74g3ahh0k0x6d5rj5rxs1lxhzx81vgdd-baloo-5.95.0/bin/kde-systemd-start-condition --condition "baloofilerc:Basic Settings:Indexing-Enabled:true"
```

`kde-systemd-start-condition` is provided by the "plasma-workspace"
derivation which depends on "baloo".

Replace the CMake macro with the generic current system's path to fix
service startup and to avoid a recursive dependency.
