chainlint: match "quoted" here-doc tags

A here-doc tag can be quoted ('EOF'/"EOF") or escaped (\EOF) to suppress
interpolation within the body. chainlint recognizes single-quoted and
escaped tags, but does not know about double-quoted tags. For
completeness, teach it to recognize double-quoted tags, as well.
