Since modinfo support was added, Meson fixed several issues with
extract_objects and compile_commands.json lookups can be simplified.
If the lookup uses the object file as key, there is no need to use the
command line to distinguish among all entries for a given source.
Ninja 1.9 is required in order to produce the 'output' key in
compile_commands.json; it is available in CentOS Stream 9, Debian 11, SLES
15.2, Ubuntu 20.04 and in all recent BSD distros. Samurai also has it.
