cmd/icingadb: Log Icinga DB version during startup

To better recognize the Icinga DB version used in case of errors, it is
now logged at startup.

If VCS is available during build, the current commit is included.
- Dirty VCS directory:
> 2024-03-11T14:36:29.317+0100    INFO    icingadb        Starting Icinga DB daemon (1.1.1-g0e9810c-dirty)
- Clean VCS directory:
> 2024-03-11T14:38:09.664+0100    INFO    icingadb        Starting Icinga DB daemon (1.1.1-geed8589)
- Build with `-buildvcs=false`:
> 2024-03-11T14:38:56.554+0100    INFO    icingadb        Starting Icinga DB daemon (1.1.1)

Closes #689.
