Use spawn_async instead of spawn_sync
The 'spawn_sync' function has been deprecated for a very long time now, but we could never use its intended replacement as its Vala bindings were broken [1]. The underlying problem had been identified in [2] a while ago, but has only been recently fixed in [3] and is now available in Vala's 0.56 branch. Since we rely on the child PID as a fallback for opinionated users or shells that are unaware of OSC 7, we have to pass a callback function to the 'spawn_async' call so we can capture the PID which is no longer supplied by the method itself.

-- Upstream recommends spawn_async() instead of spawn_sync(), but the bindings
- for it are erroneous.

- The upstream GTK devel branch has dropped some X11-specific APIs, including
the interface for urgency hints. Eventually, this feature will have to be
removed from weltschmerz too.
