Baruch Siach 721bcb8513 spidev_test: fix musl build
spidev.h needs _IOC_SIZEBITS. Add linux/ioctl.h for that to fix build under
musl.

The patch suggested upstream (https://patchwork.kernel.org/patch/9276909/)
does not apply to the spidev_test.c version we currently use. A backported
patch would break once we bump spidev_test.c. A bump+patch solution would
break if/when upstream accepts this patch. That's why this commit uses the
unusual sed patching to keep compatibility with current and future
spidev_test.c versions.
