Improve bazel builds (#53)

Improve Bazel build system of the UDFClient
- Change the configuration of compiler flags to achieve similar compiler optimization for the UDFClient than with the old build bash script
- Activate link time optimization which might allow the compiler more optimizations than before
- Remove unnecessary shared libraries for java, because these increased the loading time of the UDFClient
- Simplify the rpath workaround by moving it to the java_repository.bzl
- The build system can now build two variants of the executable, one with hard coded paths and one with a wrapper script which sets the paths via environment variables. The executable with hard coded paths only runs in the container environment, but has a few percent faster startup than the wrapper script. The wrapper script can be used local debugging and testing outside of the container environment.
