[PATCH 2/8] devconfig: Add tmux.conf copying to target systems

[Luis Chamberlain <mcgrof@kernel.org>]

Added support for copying the user's local tmux.conf configuration
to target systems during devconfig setup, following the same pattern
as gitconfig copying. If a ~/.tmux.conf file exists on the control
host, it will be copied to both the user home directory and root
home directory on target nodes.

The implementation checks for tmux.conf existence on localhost,
copies it to the target user directory if present, and then copies
to root using remote_src for efficient transfer. This ensures
consistent terminal multiplexer configuration across all development
systems.
