In d1bbbe45df (bisect--helper: reimplement `bisect_run` shell function
in C, 2021-09-13), we ported the `bisect run` subcommand to C, including
the part that prints out an error message when the implicit `git bisect
bad` or `git bisect good` failed.
However, the error message was supposed to print out whether the state
was "good" or "bad", but used a bogus (because non-populated) `args`
variable for it. This was fixed in [1], but as of [2] (when
`bisect--helper` was changed to the present `bisect-state') the error
message still talks about implementation details that should not
concern end users.
Fix that, and add a regression test to ensure that the intended form of
the error message.

In C, the natural order is for `argc` to come before `argv` by virtue of
the `main()` function declaring the parameters in precisely that order.
It is confusing & distracting, then, when readers familiar with the C
language read code where that order is switched around.
Let's just change the order and avoid that type of developer friction.

We _already_ have a function to determine whether a given `enum
bisect_error` value is non-zero but still _actually_ indicates success.
Let's use it instead of duplicating the logic.

Now that the shell script hands off to the `bisect--helper` to do
_anything_ (except to show the help), it is but a tiny step to let the
helper implement the actual `git bisect` command instead.
This retires `git-bisect.sh`, concluding a multi-year journey that many
hands helped with, in particular Pranit Bauna, Tanushree Tumane and
Miriam Rubio.
