tests: Fix test/misc/swaplabel failure due to change in mkswap behaviour.

mkswap now warns if the image file has holes. If fallocate is used to create the
file, use POSIX semantics to ensure the file has no holes.

This fixes the test failure

This avoids an extra syscall, and allows the kernel to automatically set

This changes the observable behavior of losetup --direct-io in the case
where DIO is not supported to fully fail, instead of creating a
non-direct-io device. If the user explicitly specifies --direct-io, then
they should get either a DIO loopdev or no loopdev, not a non-DIO
loopdev and a misleading error.

Additionally, loopcxt_setup_device now uses O_CLOEXEC in the read-only
fallback.

wdctl: Workaround reported boot-status bits not being present in wd->ident.options

Some watchdog drivers are capable of reporting WDIOF_CARDRESET in their
bootstatus, but they do not advertise this in the options field
returned by the WDIOC_GETSUPPORT ioctl.

This causes wdctl to not print the CARDRESET flag on these devices,
even when the reset was caused by the watchdog and this is being
reported in the WDIOC_GETBOOTSTATUS return.

Add a workaround by or-ing any bits which are set in the status and
bstatus returns into wd->ident.options so that reported flags will
get printend independent of them being advertised as supported in
wd->ident.options.

This will make wdctl print a CARDRESET line when the system was
actually reset by the watchdog while omitting it when it was not
reset by the watchdog.  At least on drivers which have the
CARDRESET is missing from info.options problem.  On other drivers
the CARDRESET line will always be printend, but the actual reported
value will change.
