cmd/git(fix[Git.rebase]): Fix whitespace options

why: The whitespace parameter emitted --whitespace without the required
value, and no_whitespace was invalid (git has no such flag). The correct
options are --whitespace=<option> and --ignore-whitespace.
what:
- Fix whitespace to emit --whitespace=<value> with the option value
- Replace no_whitespace with ignore_whitespace parameter
- Emit --ignore-whitespace for the new boolean parameter
