zebra: kernel_socket: fix 64bit MacOS X alignment
In OS X 10.7 zebra crashed on invalid execution address. sockaddr padding in *_msghdr is observed to be 4 bytes in 64bit OS X. The ROUNDUP macro assumed alignment on sizeof(long) which allocates 8 bytes on 64bit systems, 4 bytes on 32bit systems which is true for BSD generally. Test for Apple and use sizeof(int) which allocates 4 bytes on 32 & 64bit systems. Tested on 64bit OS X 10.7, FreeBSD 9.0 amd64 & i386 (32bit) using gcc & clang Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
