Prior to notary 0.6.0, notary expected a terminal and only accepted
username/password interactively. With notary 0.6.0 this can now be
passed as en environment variable 'NOTARY_AUTH' in the form of
a base64 encoded 'username:password'.
This commit removes the ugly 'expect' hack in favour of the much
cleaner use of an environment variable.

Also adjust the 'linuxkit/alpine' script to follow the
same pattern.
The new version of the script extract username/password from
the credential helper (or docker) and build and 'expect'
script to feed the info to 'notary'.
They can be invoked by:
DOCKER_CONTENT_TRUST_REPOSITORY_PASSPHRASE="phrase" ./push-manifest.sh ...
