ndisc6: patch no longer required

Now that we have 0001-remove-__FAVOR_BSD.patch in uClibc-ng (which is
upstream and will be part of uClibc-ng 1.0.26), we no longer need the
work-around patch in the ndisc6 package.

-Subject: [PATCH] trace-{tcp,udp}.c: fix build on uClibc
-
-Selection of the BSD variant of struct tcphdr/udphdr on uClibc fails
-because of config.h. This is caused by config.h setting _GNU_SOURCE
-and the compat handling (uClibc doesn't have inet6_rth_*) including
-sys/types.h which in term includes features.h, which figures out
-what bsd/gnu/posix variant to use because of:
-
- /* If _BSD_SOURCE was defined by the user, favor BSD over POSIX.  */
- #if defined _BSD_SOURCE && \
-    !(defined _POSIX_SOURCE || defined _POSIX_C_SOURCE || \
-      defined _XOPEN_SOURCE || defined _XOPEN_SOURCE_EXTENDED || \
-      defined _GNU_SOURCE || defined _SVID_SOURCE)
- # define __FAVOR_BSD    1
- #endif
-
-The current workaround of undefining _GNU_SOURCE after config.h doesn't
-work as features.h has already been evaluated by then. Instead, simply
-don't include config.h as it isn't needed in these two files.
