cli, manpage: Clean up occurrences of old image argument

--include argument was introduced and replaced --image argument in
commit 45d50a101e8073191e6d88143990ed91d3bfe815

This patch cleans up remaining few places where old `--image`
argument was mentioned so that now all the documentation has
`--include`. --image is deprecated.

Both old --image and new --include have the same short version -i
and it remains the same. The code remains the same since the code
handles --include already.

Tested by running
flashrom -h
man ./flashrom.8.tmpl
