this patch fixes run_parts when it's called by ifupdown. 1) argv has to be a
NULL terminated char* array, not just a string. 2) run_parts now explicitly
sets the environment. this environment is populated from the
/etc/network/interfaces config file and is needed by the scripts in
/etc/network/if-pre-up.d/. when run-parts is called from the command line the
environment is taken from the current process.

You can simplify this if use:

+       bb_xasprintf(&buf[0], "/etc/network/if-%s.d", opt);
+       buf[1] = NULL;
+
+       run_parts(&buf, 2, environ);
+       free(buf[0]);
