st32mon: Define SPI_IOC_WR_MODE32 if it's missing

Browse Source 
On Goobuntu, the uapi copy of spidev.h doesnot contain
SPI_IOC_WR_MODE32, however the kernel supports the IOCTL.
To be able to build the tool outside of the ChromeOS chroot,
define it if it's not available.

TEST=make buildall -j outside of the chroot
