Subject: tests: don't rely on sed -i being available

* tests/df/df-output.sh: sed --in-place is not generally available.
Also add a couple of simplifications from Bernhard Voelker.
Removing all spaces, rather than just leading spaces, suffices.
Searching for ' --output' in unadjusted df --help, suffices.
