Linux 7.0: explicitly set setlease handler to kernel implementation
The upcoming 7.0 kernel will no longer fall back to generic_setlease(),
instead returning EINVAL if .setlease is NULL. So, we set it explicitly.

To ensure that we catch any future kernel change, adds a sanity test for
F_SETLEASE and F_GETLEASE too. Since this is a Linux-specific test,
also a small adjustment to the test runner to allow OS-specific helper
programs.
