tests: add more checks of unknown ioctl command formatting

Browse Source 
* tests/ioctl.c (main): Additional check for unknown ioctl command
decoding.
* tests/ioctl_evdev.c (main): Likewise.
* tests/ioctl_dm.c: Include <linux/ioctl.h> for _IOC_SIZE and _IOC_NR.
(main) <dummy_dm_ioctl1, dummy_dm_ioctl2, dummy_dm_arg>: New constants.
Add more checks for unknown command formatting.
