ash: expand: Fix ghost fields with unquoted $@/$*

Upstream commit:

    Date: Fri, 23 Mar 2018 18:58:47 +0800
    expand: Fix ghost fields with unquoted $@/$*

    You're right.  The proper fix to this is to ensure that nulonly
    is not set in varvalue for $*.  It should only be set for $@ when
    it's inside double quotes.

    In fact there is another bug while we're playing with $@/$*.
    When IFS is set to a non-whitespace character such as :, $*
    outside quotes won't remove empty fields as it should.

    This patch fixes both problems.

    POSIX used to require the current dash behaviour.  However, you're
    right that this is no longer the case.

    This patch will remove the persistence of the variable assignment.

    I have considered the exporting the variables during the function
    execution but have decided against it because:

    1) It makes the code bigger.
    2) dash has never done this in the past.
    3) You cannot use this portably anyway.
