Since Linux kernel commit [1], the build of the iio tool has been
changed to use the common Linux tools build system. The installation
directory is now given by DESTDIR, like for all other Linux tools.
We keep the INSTALL_DIR environment in the 'install' target to be
compatible with kernels older than 4.14.
