fs/ubi: expose BINARIES_DIR to ubinize.cfg

Browse Source 
It is often necessary to refer to other images that are present in
BINARIES_DIR from a custom ubinize configuration e.g. to include the
kernel in a UBI volume.

As we do for BR2_ROOTFS_UBIFS_PATH, replace BINARIES_DIR when copying
the file.

So the volume defined for the root filesystem can specify the
image path as: image=BR2_ROOTFS_UBIFS_PATH
Buildroot also replaces the string "BINARIES_DIR" with the
value of $(BINARIES_DIR), so that it is possible to reference
other build artefacts (e.g. to include the kernel in a UBI
volume).
