realtek: fix ZyXEL initramfs image generation

The current rule produces empty trailers, causing the OEM firmware
update application to reject our images.

The double expansion of a makefile variable does not work inside
shell code.  The second round is interpreted as a shell expansion,
attempting to run the command ZYXEL_VERS instead of expanding the
$(ZYXEL_VERS) makefile variable.

Fix by removing one level of variable indirection.
