linux-libc-header: Sync CONNECTOR_MAX_MSG_SIZE with wrs kernel
Currently default header is linux-libc-header, which leads the dismatch with wrs kernel. The different headers for same file cause trouble between kerenl module and user level binary. E.g. segfault in v86d due to different CONNECTOR_MAX_MSG_SIZE in connector.h from the one used by uvesafb. This fix is work around to sync with wrs kernel headers, and should be removed after switching to linux-libc-headers-wrs. [BUGID #279] fixed by this. Signed-off-by: Zhai Edwin <edwin.zhai@intel.com>
