Add a 64 bit only product for hikey.

Also restructure some of the current make files:
- make a hikey-common.mk instead of importing hikey.mk and overriding
- don't set ro.zygote etc directly, import the helper makefiles instead

This new product avoids building all the 32 bit native executables and
libraries that gets built for the 'hikey' product. Sample benefits:
- makes the build faster
- saves ram and cpu, because there is no 32 bit zygote created
- frees up space on the system partition

Test: lunch hikey && m -j
Test: lunch hikey32 && m -j
Test: lunch hikey64_only && m -j
