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.
