support/dependencies: require at least CMake 3.8

gerbera package in version 1.3 unfortunately now requires CMake >= 3.8
for C++17 macros:
b5fd39f30f

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.

Also drop patch that relax cmake requirement on json-for-modern-cpp
