  [Glib] Getting stacktrace from systemd fails sometimes
https://bugs.webkit.org/show_bug.cgi?id=267999

Reviewed by Adrian Perez de Castro.

When `coredumpctl` is available, we use it to get the stacktrace.
The exact command executed is
`coredumpctl info --since="Wed 2024-01-24 14:48:45 CET"`.

But sometimes it fails to parse the provided datetime:
```
$ coredumpctl info --since="Wed 2024-01-24 14:48:45 CET"
Failed to parse timestamp 'Wed 2024-01-24 14:48:45 CET': Invalid argument
```

According to systemd documentation [1], we can pass the number of
seconds since the UNIX epoch prefixed with `@` instead.
