Add build script to simplify the build procedure.replicant-4.2

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.

However users still have to take care of running repo --sync
if necessary. This ensure that the local modifications are not
lost and also simplifies the procedure for testing patches.

This script is adapted from the script in Replicant 6.0
in the vendor_replicant repository which currently is touched
by the following commits:
  adf29f66 build.sh: create missing log directory
  adf29f667693147583a082c7df7440bbf1b7bb09
And:
  79c21f1b Add build script to simplify the build procedure.
