[PATCH 07/12] Makefile: Move NETNS_RUN_DIR definition to C code

[David Gibson <david@gibson.dropbear.id.au>]

NETNS_RUN_DIR is set in the Makefile, then passed into the C code with
-D.  But NETNS_RUN_DIR is just a fixed string, it doesn't depend on any
make probes or variables, so there's really no reason to handle it via the
Makefile.  Just move it to a plain #define in conf.c.
