builtin/bundle.c: let parse-options parse subcommands

Browse source 
'git bundle' parses its subcommands with a couple of if-else if
statements.  parse-options has just learned to parse subcommands, so
let's use that facility instead, with the benefits of shorter code,
handling missing or unknown subcommands, and listing subcommands for
Bash completion.
