Remove redundant path

[Spredzy]

What does this PR do?

Currently the definition of the path is redundant. If ee_builder_dir is specified we both chdir into and try that absolute path, which can't work.

The idea here is to chdir into it and looking for local execution_environment.yml

How should this be tested?

Specify ee_builder_dir
