Buildroot commit 532d5561f48b6c430e7414ba5eacccf9b6c1bd22 bumped
iproute2 to version 6.17.0 which added lib/bridge.c:
https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/log/lib/bridge.c?h=v6.17.0
and causes build errors on musl & uclibc toolchains.

Added upstream patch to fix the problem.

+Subject: lib: bridge: avoid redefinition of in6_addr
+
+On musl libc, which does not use the kernel definitions of in6_addr, including
+the libc headers after the kernel (UAPI) headers would cause a redefinition
+error. The opposite order avoids the redefinition.
