Ensure /var/lib/hardware/udi exists and with 755 permissions

We make this fix in Makefile at installation time so that the
directory gets removed upon purging the package and doesn't
linger on.

This fixes any save-config issues one may see on Linux
distributions where the directory doesn't exist by default.
