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.
