parser: Fix backquote support in here-document EOF mark

parser: Fix backquote support in here-document EOF mark
Currently using backquotes in a here-document EOF mark is broken
because dash tries to do command substitution on it. This patch
fixes it by checking whether we're looking for an EOF mark during
tokenisation.
Reported-by: Harald van Dijk <harald@gigawatt.nl>
Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
With added fix for quoted-ness of the EOF mark.
