make-initrd.sh: add busybox, socat and mount.nfs4 to LDD_BINARIES

make-initrd.sh will use ldd to get the share library list from LDD_BINARIES.
And this code can handle static link binary with itself.
So add busybox, socat and mount.nfs4 to LDD_BINARIES to make make-initrd.sh
support different binary.
