builtin rebase: support --allow-empty-message option

This commit introduces the `--allow-empty-message` option to
`builtin/rebase.c`. The motivation behind this option is: if there are
empty messages (which is not allowed in Git by default, but can be
imported from different version control systems), the rebase will fail.

Using `--allow-empty-message` overrides that behaviour which will allow
the commits having empty messages to continue in rebase operation.

Note: a very recent change made this the default in the shell scripted
`git rebase`, therefore the builtin rebase does the same.
