Do not correct RPATH, it doesn't work when doing a venv

When doing a venv, it's going to copy the `python` binary, but not the `libpython.so` library. If the RPATH is relative to the binary, it's not going to find the library at `$ORIGIN/../lib` and it will fail to start. Instead, keep the RPATH absolute.

Also manually add the python -> pythonX.Y and pip -> pipX.Y symlinks, projects depend on them.
