spi: spidev_test: fix build with musl libc
spidev.h uses _IOC_SIZEBITS directly. musl libc does not provide this macro
unless linux/ioctl.h is included explicitly. Fixes build failures like:
In file included from .../host/usr/arm-buildroot-linux-musleabihf/sysroot/usr/include/sys/ioctl.h:7:0,

ret = ioctl(fd, SPI_IOC_MESSAGE(1), &tr);
