git p4: remove submit failure options [a]pply and [w]rite

When a patch failed to apply, these interactive options offered
to:

    1) apply the patch anyway, leaving reject (.rej) files around, or,
    2) write the patch to a file (patch.txt)

In both cases it suggested to invoke "git p4 submit --continue",
an unimplemented option.

While manually fixing the rejects and submitting the result might
work, there are many steps that must be done to the job properly:

    * apply patch
    * invoke p4 add and delete
    * change executable bits
    * p4 sync -f renamed/copied files
    * extract commit message into p4 change description and
      move Jobs lines out of description section
    * set changelist owner for --preserve-user

Plus the following manual sync/rebase will cause conflicts too,
which must be resolved once again.

Drop these workflows.  Instead users should do a sync/rebase in
git, fix the conflicts there, and do a clean "git p4 submit".
