The meson command line has -Dbuild_tests=disabled -Dwith_libdrm=""
because those aren't trivial to make automatic. Plain libdrm is also
required, but the libdrm_vendor ones are all optional so for now those
are just explicitly disabled. Otherwise this tests that the automated
machinery is able to figure out what can be built.

v2 (Simon): Base the debian docker image on the debian-minimal image

v3: Make the empty argument to with_libdrm more explicit and apparent (Arek)
