iproute2: fix header problem for musl

iproute2 includes "sanitized" linux kernel headers, which work fine for uClibc, however
with musl there is some header conflict, principally some ipv6 structure redefinition.  This
patch removes <linux/in6.h> from include/linux/if_bridge.h to solve the problem.
