[PATCH] xfstests: tests/generic: added -P option to df

[Stanislav Kholmanskikh <stanislav.kholmanskikh@xxxxxxxxxx>]

Otherwise the testcases will fail if the scratch
device has a long name (for example, if it's an LVM volume).
Because df outputs its usage stats with two lines:

/dev/mapper/xfstests-disk1
                       3030800      4608   2868908   1% /tmp/mnt/disk1
