Commit 8c96cfbfe530 ("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. Do
the chattrs everywhere, which gets these tests running on kernels
supporting Btrfs swapfiles.

Should this get refactored into a _format_swapfile or something, rather
than open coding this everywhere?
_format_swapfile() {
local fname=$1
local sz=$2
touch $fname
chmod 0600 $fname
chattr +C $fname > /dev/null 2>&1
_pwrite_byte 0x61 0 $sz $fname >> $seqres.full
mkswap -U 27376b42-ff65-42ca-919f-6c9b62292a5c $fname >> $seqres.full

Similar to generic/356 that makes sure we can't reflink an active
swapfile.

Swap files cannot have holes, and they must be at least two pages.
swapon(8) and mkswap(8) have stricter restrictions, so add versions of
those commands without any restrictions.
