Summary [GLib] Process launching hangs if xdg-dbus-proxy is not installed

In https://gitlab.gnome.org/GNOME/gnome-build-meta/-/issues/685 we discovered that process launching hangs if xdg-dbus-proxy is not installed. This is because we do a synchronous read() at the bottom of XDGDBusProxy::launch, and it never completes if spawning bwrap failed.

Current behavior is we print the following and then hang forever: bwrap: execvp /usr/bin/foo: No such file or directory Proposed behavior is to print then crash (because this is not recoverable): bwrap: execvp /usr/bin/foo: No such file or directory ** (epiphany:203869): ERROR **: 15:49:53.627: Failed to fully launch dbus-proxy: Child process exited with code 1 Trace/breakpoint trap (core dumped)
