Subject: qtwebengine: link to pulseaudio

Nix builds of QTWebEngine doesn't support sound output via Pulse, only
through ALSA, unless sandboxing is disabled and LD_LIBRARY_PATH
contains a reference to the Pulse libraries.

By default, Chromium won't link to PulseAudio, but dlopens it in
run-time. It is tricky to make this work because of the nontrivial
sandbox configuration. Nix builds of Chromium already link against
Pulse directly, so it makes sense to copy this behavior in
QTWebEngine.
