Test the behaviour of Dune querying git when the repo has no commit.

Create a repository with no HEAD commit:

$ git init --quiet

... and an executable that links `dune-build-info':

$ echo "(lang dune 2.0)" > dune-project
$ touch main.ml
$ cat >dune <<EOF
> (executable
> (name main)
> (libraries dune-build-info)
> (promote (until-clean)))
> EOF

At the moment Dune fails, which is bad:

$ dune exec ./main.exe 2>&1 | sed 's/.*\/git/{{ git }}/; s/> .*.output/> {{ output_file }}/g'
git (internal) (exit 128)
{{ git }} describe --always --dirty > {{ output_file }}
fatal: bad revision 'HEAD'
