ash: expand: Ensure result is escaped in cvtnum

Upstream commit:

    Date: Fri, 1 Jun 2018 18:25:29 +0800
    expand: Ensure result is escaped in cvtnum

    The minus sign generated from arithmetic expansion is currently
    unquoted which causes anomalies when the result is used in where
    the quoting matters.

    This patch fixes it by explicitly calling memtodest on the result
    in cvtnum.
