config: remove explicit undef of unset values

Rather than explicitly clearing any setting of undefined values in our
rte_config.h file, it's better to instead just add a comment that the
value is not set. Using a comment allows the user to set the value using
CFLAGS or similar mechanism without the config file clearing the value
again.

The text used "<VALUE> is not set" is modelled after the kernel approach
of doing the same thing.
