From the main commit:

The virtual pipeline is very helpful for debugging purposes and very
small. One big reason to not build it by default in the past was likely
the libyuv dependency, which many distros did not ship by default.

By now big distros like Debian, Fedora, and others ship libyuv and
already use it when building libcamera. Fedora even enables both test
pipelines by default.

Thus let's build the virtual pipeline by default, facilitating libcamera
adoption.

Changes in v2:
 - Reintroduced libjpeg dependency for libyuv subproject
 - Collected tags

  pipeline: virtual: Move libjpeg requirement to libyuv subproject

Hi Robert,

Note that RHEL (i.e. the other big long-term supported distro) does not 
ship libyuv and that EPEL 10 is missing the package at the moment:
- https://packages.fedoraproject.org/pkgs/libyuv/libyuv/
- https://bugzilla.redhat.com/show_bug.cgi?id=2344526

Best,
Christian
