ash: parser: Fix parsing of ${}

parser: Fix parsing of ${}
dash -c 'echo ${}' should print "Bad subtitution" but instead
fails with "Syntax error: Missing '}'". This is caused by us
reading an extra character beyond the right brace. This patch
fixes it so that this construct only fails during expansion rather
than during parsing.
