keepalived: fix recvmsg/sendmsg on mips64 again

Browse source 
Commit e73964fa8f incorrectly dropped the
patch 101-update-struct-msghdr.patch. Add it again, and while add it
also add the follow-up patch that was added upstream.

Fixes #3757.

Subject: [PATCH] vrrp: update struct msghdr
The vrrp netlink code assumes an order for the members of struct msghdr.
This breaks recvmsg and sendmsg with musl libc on mips64. Fix this by
using designated initializers instead.

Subject: [PATCH] Reinstate initialisation of msghdr fields
Commit dbb2cac removed initialisation of the struct msghdr msg_control,
msg_controllen and msg_flags fields. This commit reinstates initialisation
of those fields.
