envtools: make sure version/timestamp header file are available
With commit 84d46e7e8948 ("tools: env: allow to print U-Boot version")
the fw_env utilities need the version.h header file. Building only
the envtools in a pristine build directory will fail due to missing
header files.
Make sure the header files are a dependency of the envtools target.
