[Buildroot] [PATCH] support/dependencies: require at least CMake 3.8

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

The json-for-modern-cpp package unfortunately now requires CMake >=
3.8, so we need to bump our requirement from 3.1 to 3.8. If the host
doesn't have a CMake >= 3.8, Buildroot will build its own host-cmake
package.

Fixes:
