Subject: [PATCH] fix build with musl C library

With musl C library, we get following build error:

/home/buildroot/autobuild/run/instance-3/output/build/let-me-create-v1.5.2/src/core/spi.c: In function 'spi_transfer':
/home/buildroot/autobuild/run/instance-3/output/build/let-me-create-v1.5.2/src/core/spi.c:170:19: error: '_IOC_SIZEBITS' undeclared (first use in this function)
if (ioctl(fd, SPI_IOC_MESSAGE(1), &tr) < 0) {
^
/home/buildroot/autobuild/run/instance-3/output/build/let-me-create-v1.5.2/src/core/spi.c:170:19: note: each undeclared identifier is reported only once for each function it appears in

Include <linux/ioctl.h> for musl C library compatibility.
