In some cases, a development tree doesn't have a .git root
(for example, when a source monorepo is assembled using the
duniverse vendoring tool). In this situation, instead of
leaking an exception, the gen_version tool with just stamp
the "unknown" version and let the build continue.

Looks good to me, maybe it's worth adding en entry in the changelog saying that version is now unknown in absence of a git root? (even if it's a fix)

this'll be superseded by #1133 which I intend to refresh soon but it's nice to have a solution in the meantime.

Note that this solution means that all versioned .ocamlformat files will fail because of a version mismatch, but that's already the case in a duniverse.
