[TESTING] Kodi 18 (Leia) builds for Vero 2 & 4K

17.8-150, 22 Dec 2017: Based off OSMC commit (e0574bc7) and xbmc (7b1ff231)

OSMC:
Add initial OSMC helper routines to Kodi core library to improve implementation on OSMC (e0574bc7)
This fixes the Netflix addon error for the Vero 4k (If you previously installed Netflix addon for the 4k you will need to remove and reinstall addon)
​​​​​​​

To install Netflix plugin you will need to manually install the dependencies first. See guide from @joakim_s
