Max Reitz 57284d2ada iotests: Enable fuse for many tests
Many tests (that do not support generic protocols) can run just fine
with FUSE-exported images, so allow them to.  Note that this is no
attempt at being definitely complete.  There are some tests that might
be modified to run on FUSE, but this patch still skips them.  This patch
only tries to pick the rather low-hanging fruits.

Note that 221 and 250 only pass when .lseek is correctly implemented,
which is only possible with a libfuse that is 3.8 or newer.
