main/sxmo-common: allow switching between pipewire and pulseaudio (MR 3711)

Users can switch to pulseaudio with:
  doas apk add sxmo-audio-common-pulse

We can make the poco f1 device APKBUILD depend on
sxmo-common-audio-pulse. This allows you to install pulseaudio on Sxmo
which was the reason Joel said the poco f1 was having issues with call
audio: https://gitlab.com/postmarketOS/pmaports/-/issues/1821

After installing pulseaudio with this patch, the other side still
cannot hear me. I am posting this work so that others can just run
pulseaudio on sxmo and find out what's causing this bug.

Note by ollieparanoid: while it doesn't fix the bug completely, it seems
it's required to make calling work again, something we definitively want
to have in v22.12 so I'm merging this now. Also the sxmo-utils patch was
merged to sxmo-utils upstream, but isn't in alpine yet. Adding this
package (previous patch) temporarily makes sense.
