Commit 8c96cfbfe5 ("generic/35[67]: disable swapfile tests on
Btrfs") disabled the swapfile tests on Btrfs because it did not
support swapfiles at the time. Now that we're adding support, we
want these tests to run, but they don't. _require_scratch_swapfile
always fails for Btrfs because swapfiles on Btrfs must be set to
nocow. After fixing that, generic/356 and generic/357 fail for the
same reason. After fixing _that_, both tests still fail because we
don't allow reflinking a non-checksummed extent (which nocow
implies) to a checksummed extent.
Add a helper for formatting a swap file which does the chattr, and
chattr the second file, which gets these tests running on kernels
supporting Btrfs swapfiles.

Btrfs doesn't support swapfiles (yet?), so generic/356 fails
erroneously, and generic/357 only passes by accident. Let's add a
_require_scratch_swapfile helper and add it to these tests.

Since none of the current filesystems support reflinked swap files,
make sure that we prohibit reflinking of swapfiles and swapon of
reflinked files.
