Title: v4l2: add format negotiation and OpenBSD support

Changes are:
* `libv4l2` is not required for proper operation any more
(it is still desirable, as it guarantees that librem-supported format will
be available);
* `v4l2` module now iterates through the list of available formats and settles
on first one supported by librem;
* if `libv4l2` is present, baresip will try to use native format and fall back
to emulated one only if no usable combination found.
