Ian Campbell 6c1ba442b4 update-component-sha.sh: ignore changes in directories named "vendor"
src/cmd/linuxkit/vendor/github.com/moby/tool/src/moby/linuxkit.go embeds a yaml
fragement with some hashes in it, so avoid updating that since that would make
the vendoring unclean.

$0 --<mode> <how-to-find> <new-hash>
Available modes: --hash and --image
Replace by hash:
$0 --hash <OLD> <NEW>
Example: $0 --hash 8675309abcdefg abcdef567899
Will replace all instances of 8675309abcdefg with abcdef567899
Replace by image: $0 --image <IMAGE> <NEW>
$0 --image <IMAGE> <NEW>
Example: $0 --image linuxkit/foo abcdef567899
Will tag all instances of linuxkit/foo with abcdef567899
$0 --image <IMAGE>:<NEW> is accepted as a convenient shortcut for cutting
and pasting e.g.the output of linuxkit pkg show-tag
By default, for convenience, if no mode is given (--image or --hash), the first method (--hash) is assumed.
Thus the following are equivalent:
$0 <OLD> <NEW>
$0 --hash <OLD> <NEW>
