Subject: [PATCH] ts-libvirt-build: Rework to build with meson

libvirt have switch build system to Meson + Ninja, there is no more
autogen.sh script.

Add missing dependency "libtirpc-dev" and "meson".

libvirt needs at least meson 0.54, the version avaiable in Debian
Buster is too old, but we can install it from backports.

In order to find out if Meson is used or not, we'll check if the
"autogen.sh" script is missing. And in the build dir, we will look for
a "Makefile".
