[Replicant] [PATCH][v2] Add build script to simplify the build procedure.

[Denis 'GNUtoo' Carikli]

Once the source code is downloaded and the dependencies are
installed, it makes it easier for people to build Replicant.

It also saves the builds logs, to enable to later look at why
the build failed without needing to re-run the build.
