[libvirt] [jenkins-ci PATCH 01/17] guests: Deal with multilib path

[Fabiano Fidêncio]

When building a project using Meson, the project will be installed
respecting the multi-library path.

In order to get the right path we should do:
- Debian based machines:
  - Use the value of `dpkg-architecture -q DEB_TARGET_MULTIARCH`
- RPM based machines:
  - Use the value of `rpm --eval '%{_lib}'`
