I mean that we should rather than hacking around it in the tests handle
EOPNOTSUPP properly in the test libray when mounting filesystems. We do
enough magick in safe_mount() to support FUSE and handle other corner
cases, checking for EOPNOTSUPP (possibly with non-standard mount flags)
does sound like a reasonable extension.

The main point of handling the filesystems in the test library is that
cleanup (umounting) is handled properly even if the test crashes. If we
move the code back to the tests like this we lose that.
