tests: check decoding of RTC_* ioctls
* configure.ac (AC_CHECK_FUNCS): Add ioctl_rtc. * tests/ioctl_rtc.c: New file. * tests/ioctl_rtc-v.c: Likewise. * tests/ioctl_rtc.test: New test. * tests/ioctl_rtc-v.test: Likewise. * tests/.gitignore: Add ioctl_rtc and ioctl_rtc-v. * tests/Makefile.am (check_PROGRAMS): Likewise. (DECODER_TESTS): Add ioctl_rtc.test and ioctl_rtc-v.test.
