Subject: app: Work around pkexec restriction when launching

Unless automatic child reaping is disabled in GSpawnFlags, glib's
g_spawn_* functions will reparent the spawned process to init by
double-forking. Unfortunately pkexec bails out in this case[0],
which means that it no longer works in .desktop files since the
PID tracking removal in commit 01c6392c1373.
Fix this by going back to manual child reaping.
