travis: zephyr: Use cmake makefile generator.

MaureenHelm · MaureenHelm · commit 3b88c478d49f · 2020-10-13T09:28:18.000-05:00
The core cmake rules don't generate valid a ninja build system due to
their use of C_INCLUDES, C_FLAGS, and C_DEFINES. Update the zephyr port
documentation and travis to use the makefile generator.
