[PATCH v2] gitlab-ci: publish test report as an artifact

[Paolo Bonzini]

Since version 0.55, "meson test" produces JUnit XML in the meson-logs
directory.  The XML can be parsed by GitLab and showed as part of the
CI report.

However, if the build and tests are performed by "meson dist",
the tests are performed in "meson dist"'s own build directory
and the logs are not accessible.  So switch from "ninja dist"
to "meson dist --no-tests" after a separate build step that
is shared by the normal and the DIST=skip cases.

	v1->v2: only do it for new-enough distros

	For an example see
	https://gitlab.com/bonzini/libvirt/-/pipelines/221545357/test_report.
	Test durations however are not yet available in upstream Meson.
