rev-list: move show_commit() to the bottom

The `show_commit()` function already depends on `finish_commit()`, and
in the upcoming commit, we'll also add a dependency on
`finish_object__ma()`. Since in C symbols must be declared before
they're used, let's move `show_commit()` below both `finish_commit()`
and `finish_object__ma()`, so the code is cleaner as a whole without the
need for declarations.
