George G. Davis 8f9577eda5 selftests: watchdog: Validate optional file argument ...

The newly added optional file argument does not validate if the
file is indeed a watchdog, e.g.:

./watchdog-test  -f /dev/zero
Watchdog Ticking Away!

Fix it by confirming that the WDIOC_GETSUPPORT ioctl succeeds.
