bisect: simplify building "checkout" argument list

Browse Source 
Reduce the scope of argv_checkout, which allows to fully build it during
initialization.  Use oid_to_hex() instead of oid_to_hex_r(), because
that's simpler and using the static buffer of the former is just as safe
as the old static argv_checkout.
