tests: fix regex to match "-" in ipcent field in df/total-verify.sh

The regular expression failed to match for file systems that
do not provide inode statistics, e.g. VFAT or CIFS (depending
on the underlying peer file system).

* tests/df/total-verify.sh: Fix the regular expression to match
a dash in the ipcent field again.

Reported by Assaf Gordon in http://bugs.gnu.org/13099.
Bug introduced in commit v8.20-18-gdae8d22.
