[PATCH] parser: Fix here-doc EOF marker bug with negative chars

[Herbert Xu <herbert@xxxxxxxxxxxxxxxxxxx>]

The here-document EOF marker parsing code incorrectly treats all
negative bytes as EOF instead of just PEOF.  Fix this by testing
against PEOF.

Fixes: 81daadfce8d5 ("[PARSER] Removed noexpand/length check on eofmark")
