[rqlrewrite] Test and fix potential NameError
We were referencing a loop variable, which may lead to a name error and show a
potential error if there are several matching variables.
To avoid this, introduce a list to hold every encountered variable and process
all of them later.
#!/bin/sh -e
if [ "$1" = "purge" ] ; then
rm -rf /etc/cubicweb.d/
rm -rf /var/log/cubicweb/
rm -rf /var/lib/cubicweb/
fi
