ABCL's build calls the hostname command, and needs the internet to download
JUnit. Neither of these are really required, though, so we can patch them out
to make it build.

We also remove the Implemetation-Build property that ends up in the manifest
file, because it stores information about the time of the build, which makes
it non-deterministic.
