test_build.sh: Move build test procedure to repository

Instead of hard coding the test procedure on qa.coreboot.org, allow
running a script in the repo instead. The server is already adapted
to do that, so once there's a test_build.sh file in the toplevel
directory, it's run in place of the default operation.

The content of this change mirrors the default operation exactly so
should serve as a good starting point.

The script is executed in an encapsulate[0] context with the workspace,
/tmp and $HOME/.ccache writable, everything else read-only and
network disabled.

It should return 0 on success, anything else on failure, as is normal
for UNIX processes.
