Inconsistent install_bins folder location behaviour in esm_runscripts

[JanStreffing]

I'm on branch: https://github.com/esm-tools/esm_tools/tree/feat/awiesm3-v3.4, currently on commit: 37d3b08

In esm_master for setups the install_bins variable is used to copy binaries from various component models into model_codes/$setup_name/bin/.

For lpj_guess within awiesm3 we configure like this:

        model_dir: ${general.model_dir}/sources/LPJ-GUESS-lpjg_v4p1/
        destination: lpj_guess
        install_bins: sources/LPJ-GUESS-lpjg_v4p1/build/guess_T159
        executable: guess_T159

My expectoration would be, that esm_runscripts tries to copy the executable from model_codes/$setup_name/bin/ to the work run bin dir. However, the error messages I get for awiesm3 suggests overwise:

================================================================================
STARTING SIMULATION JOB!
Experiment ID = test8
Setup = awiesm3
This setup consists of:
- fesom
- oifs
- rnfmap
- lpj_guess
- oasis3mct
- xios
Experiment is installed in:
       /work/ab0246/a270092/runtime/awiesm3-v3.4//test8
================================================================================
File not found: /work/ab0246/a270092/model_codes/awiesm3-v3.4/sources/LPJ-GUESS-lpjg_v4p1/build/guess_T159

Working paths would have been the one that the binary is originally installed in by cmake:
/work/ab0246/a270092/model_codes/awiesm3-v3.4/lpj_guess/sources/LPJ-GUESS-lpjg_v4p1/build/guess_T159
and the one that esm_master copies it to:
/work/ab0246/a270092/model_codes/awiesm3-v3.4/bin/guess_T159

Instead, esm_runscript seems to be relying on the model make/cmake setups installing binaries in the bin/$executable format/path. Only in this case, does esm_runscripts pick them up from the right location relative to the model_codes/$setup_name/bin dir.

My current workaround is to just copy the binary to where esm_runscripts is looking for it, but a fix is needed. Let me know if I configured anything wrong here.
