bootctl: Plumb in the feature

The code is present but is not currently enabled. Add Makefile rules
so that it is built. Also add a gitignore for bootctl.ini since this
file is created when 'bootctl run' is used.

Update the Kconfig rule to disable this by default, except for sandbox
the EFI app. Add a dependency on CMDLINE since the textline object
calls cread_line_process_ch() which is otherwise not available.
