[libcamera-ci] [RFC PATCH v2 4/4] Add job to run lc-compliance on the virtual pipeline handler

[Barnabás Pőcze]

Add a new job named `lc-compliance:virtual` that uses the
build artifacts created by the `build-package:debug` job
on amd64 to run `lc-compliance` on the "Virtual0" camera
in a virtual machine.

The `force_fallback_for=gtest` option is needed because `cpp_debustl`
makes ABI incompatible changes in the STL containers, so googletest
also needs to be compiled with these changes.

Changes in v2:
  * publish lc-compliance results to gitlab
  * add and use script to install libcamera binary package
