rc git: don't require client in git show-diff

This fails because the new logic wrongly assumes the presence of a client:

    hook global WinCreate /.* 'git show-diff'

The "diff" process hangs because we never write to ${kak_response_fifo}.
After a "pkill diff", the *debug* buffer shows

    error while waiting for shell: 1:1: 'evaluate-commands': 3:13: 'execute-keys': no such client: '-draft'
    shell stderr: <<<

The client argument is completely unnecessary since we always want
to use the calling context's buffer anyway. Remove it.

Note that we can probably further simplify this by using "write"
instead of a shell process. I'll send that patch along a few other
error handling improvements later.

Closes #5235
