[bug#63802] [PATCH 3/3] client: Use mumi git-send-email-headers subcommand.

[Arun Isaac <arunisaac@systemreboot.net>]

* mumi/client.scm (send-email): Accept mumi-command argument and use
it to construct --header-cmd.
* scripts/mumi.in: Pass command to send-email.
* tests/client.scm ("send patches to new issue", "send patches to
existing issue", "send single patch to new issue", "send single patch
to existing issue", "send patch to existing issue and Cc other
participants"): Adjust tests.
