tests: check decoding of EVIOC* ioctls
* tests/ioctl_evdev.c: New file.
* tests/ioctl_evdev-v.c: Likewise.
* tests/ioctl_evdev.test: New test.
* tests/ioctl_evdev-v.test: Likewise.
* tests/.gitignore: Add ioctl_evdev and ioctl_evdev-v.
* tests/Makefile.am (check_PROGRAMS): Likewise.
(DECODER_TESTS): Add ioctl_evdev.test and ioctl_evdev-v.test.
