[PATCH] doc: git-rebase: Update incompatible options

[Omri Sarig <omri.sarig13@gmail.com>]

Several options in the rebase man page were described as incompatible,
where this is no longer the case:

- Commit 1a66d8c6f658051a02b6d8f024e80e06fccdcd11 removed
  `--allow-empty-message` for the incompatible option list, but did not
  update the the documentation of the option itself.
- Commit a74b35081c51adbde3ef01870ba03e859db33be6 removed the
  `--preserve-merges` option from rebase, which removes all
  incompatbiilty references to `--ignore-date, --reset-author-date` and
  `--signoff`.

Update the description of these option, to no longer reference the
INCOMPATIBLE OPTIONS section.

I've also found out that the option `--onto` is now mentioned in the
INCOMPATIBLE OPTIONS section, but is not referencing it from its own
documentation. If this is not intentional, I'll happily send another patch/V2
to address this issue as well.
