Change Details

Replace `autotools` by `cmake` for the linux gitian builds, and use `ninja` as a generator. Note 1: The `test_bitcoin` binary is no longer part of the gitian output. Note 2: There are some more dependencies required. This is because CMake is run for the native platform in order to build a couple helper binaries for secp256k1 and univalue. CMake is run from the project root and check for all the dependencies despite only a compiler is required. This is a minor inconvenience which can be reworked later. Depends on D4425.
