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.
