generic/571: skip test if locktest -t on NFS returns EAGAIN

As kernel commit e93a5e9306a5 ("NFSv4: Add support for application
leases underpinned by a delegation") describes, NFS now supports
file leases only after delegations.  However, fstests lacks many NFS
functionalities including delegation.

So let's skip generic/571 if locktest -t on NFS returns EAGAIN
because of commit df2c7b951f43 ("NFSv4: setlease should return
EAGAIN if locks are not available").
