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.
